segfault when splitting window

[Wayne]

upon open a terminator session, when i try to 'split' either vertical or horizontal, it will just close the window entirely.

[chantra (chantra)]

Hi Wayne,

Thanks for reporting this bug.

Can you start terminator from the command line and send us the output that is generated when splitting the terminal.
Also, what version of terminator are you running and on what distribution.
cheers

[Wayne (wlee618)]

all it says is 'segment fault' and the version is 0.8.1...
i did the sudo ./setup.py install to install...

Wayne: could you provide a little more detail about the system you are running terminator on?
The segfault is python itself crashing, so if it is our fault we need to know why it's happening so we can work around it, but realistically something like python should never segfault.

[Wayne (wlee618)]

hi Chris,
sorry, i am using ubuntu 8.04. please let me know what else i can do to let
you take a look or what recovery commands...

thanks

Terminator is available in Ubuntu 8.04, so you should be able to install it from the "All available applications" section of Applications->Add/Remove...
However, I strongly suspect that doing it that way will stop it segfaulting. On one hand I'd like to get your issue sorted as quickly as possible, but I'd also like to know why it's segfaulting!

[Wayne (wlee618)]

i have also installed the terminator by 'apt-get install terminator'..
shouldn't that be doing the same thing? i will go ahead and try that... i
doubt it will fix that issue..

Is this still a problem? Did a package install fix it?

nope.. still the same. nothing changed.

[Chris Jones (cmsj)]

Wayne: In that case, could you download the current trunk and see if it still happens? (you can do this by installing the "bzr" package, running "bzr branch lp:terminator" and then running ./terminator from the "trunk" directory. I'm very curious to find out what is causing python to segfault!

[Wayne (wlee618)]

hi Chris,
if you meant to run the terminator fromthe use/bin/ dir, then i did. i got
bash: setenv: command not found
bash: setenv: command not found
when i did that "./terminator"
then i did the 'CTRL-Shift-E' i got..
(terminator:7274): Vte-WARNING **: No handler for control sequence
`device-control-string' defined.
Segmentation fault

hope that helps..

thanks
is that what you are looking for?

Thanks Shang. I've pushed a small change to trunk which may help here, but ultimately I think it would be really helpful if you could run terminator in gdb and when it segfaults, get a backtrace.

[Shang Wu (shangwu)]

This is the backtrace for the old program, will try the new trunk later.

[Shang Wu (shangwu)]

And the latest trunk failed as well, attach with the backtrace file.

[Wayne (wlee618)]

hi guys,

do i need to do anything with this?

thanks

Not at the moment thanks, we're trying to get out some useful debugging
information.

[Chris Jones (cmsj)]

Shang: I'm not entirely sure it will help very much in the short term, but it would be useful if we could get a backtrace with enough -dbg packages to resolve all the library symbols

[Shang Wu (shangwu)]

Chris,

I used the valgrind to generated the debug information against the latest trunk, I hope it has enough information to troubleshoot the issue.

[Shang Wu (shangwu)]

Also, here is the strace file, if it helps any. Please let me know if anything else would help.

[Shang Wu (shangwu)]

Here is the dpkg -l | grep lib list.

[Chris Jones (cmsj)]

Thanks Shang. I have added some more debugging to trunk to try and figure out exactly what is triggering this - could you grab the latest trunk and test again? (either just the output of Terminator or another strace is fine)

[Shang Wu (shangwu)]

[Chris Jones (cmsj)]

Thanks very much Shang. We now have enough debugging to know exactly which pygtk call is causing the segfault. It's in TerminatorTerm.add() near the beginning:

      widget.reparent (pane)

[chantra (chantra)]

Hi shang,

I slightly modified this bit of code, can you try out the latest trunk.

Does it fixes your issue?

cheers

That's a no.

[Chris Jones (cmsj)]

Shang, I just pushed the debugging back in, could you pull and try again. I want to be sure it's dying in the same place.

[chantra (chantra)]

Shang, can you try the following script.
Click on the button
does it segfault?

cheers

[chantra (chantra)]

shang,

I also found that: http://osdir.com/ml/gnome.gtk+.python/2005-02/msg00161.html
It is all, but I wonder if this could be related.
Could you also check that python code: http://osdir.com/ml/gnome.gtk+.python/2005-02/txtFmI4zT7YHr.txt
does it segfault? it did not on my lappy
cheers

[chantra (chantra)]

Shang,

yet again, what does happen if you first open a new tab (ctrl-shift-t)
and then split?

does it fail when opening a new tab, or when splitting? or not at all :)

cheers

I'm going to mark this bug as Invalid for terminator because I think it's a bug in vte. Even if we are doing something wrong, this shouldn't segfault in a C library. Added vte as an affected distribution package

[Wayne (wlee618)]

So u r saying all users with ubuntu 8.04
 Has this problem?

Wayne: No, this isn't affecting all Ubuntu 8.04 users - I run Terminator on two 8.04 machines. one was a fresh install, one was an upgrade. Shang is able to reproduce it on 8.04 machines, but I can't, so there is some deeper mystery here, but I'm pretty sure it's not Terminator's fault, and unfortunately I don't think we can work around it from Terminator.

is there any work around? you are not telling me to 'too bad, you are

Wayne: we tried a workaround, but it didn't make any difference, we seem to be hitting a lower level bug, so for the moment I'm afraid there's not very much we can do. I'm trying to get hold of the relevant people in the GNOME project to figure out what's going on because this is possibly fixed upstream already. I'm very sorry and I do feel bad about not being able to fix this bug. It's especially frustrating that I can't even reproduce it.

[Chris Jones (cmsj)]

I decided that while the bug isn't ours, I'm still going to leave this as a Confirmed, Critical bug for us, at least partly so it stays on my radar.

[Wayne (wlee618)]

thank you! there was a reason i like open source software.. :)

It would be good if someone having the issue could send this to the upstream maintainers at bugzilla.gnome.org for forwarding intructions please have a look to https://wiki.ubuntu.com/Bugs/Upstream/GNOME ; thanks in advance.

[Chris Jones (cmsj)]

Is anyone still able to reproduce this? Shang has indicated that after upgrading to Intrepid (and thus terminator 0.11) he is able to split the window now.

[Chris Jones (cmsj)]

On further investigation with Shang it seems to relate to combinations of encoding and titlebar setting.

Shang: could you elaborate on exactly which combinations do and do not crash, please?

[Shang Wu (shangwu)]

In 8.10, I was able to reproduce the issue by:

1. Open the terminal
2. Check if the Show title is enabled by right click on the window. If it is, right click to open a split window.
3. Disable show title on both window, and close the window.
4. And when I try to run terminal again, try the split window, I get the segmentation fault.

It seems it require to have the show title set, in order to split the window.

[Chris Jones (cmsj)]

I have a theory which might help with this. Would you be able to grab the latest trunk (bzr branch lp:terminator) and apply the attached patch please?

[Shang Wu (shangwu)]

Hi Chris,

Sorry for the delay, however, since I upgraded to 9.04, the issue doesn't seem to occured anymore...

Thanks for your help,

[Chris Jones (cmsj)]

I'm going to mark this bug Invalid. Someone please re-open it if you can still reproduce this.
