xchat-gnome crashes on 'save transcript' on blank screen

[Stevie Beth Mhaol]

Binary package hint: xchat-gnome

Steps to reproduce the crash:
1. load xchat-gnome
2. type ctrl-s OR discussion->save transcript

Expected result:
A save dialog, or maybe that the option is disabled until there's some text in the buffer.

Actual result:
Segfaults every time.

Here is the gdb backtrace i get when this bug is triggered.

[Daniel Holbach (dholbach)]

Thanks for your bug report. Which version of Ubuntu do you use? Can you get another backtrace with libgtk2.0-0-dbg libglib2.0-0-dbg and libc6-dbg installed?

[Guillaume Desmottes (cassidy)]

I can't reproduce this bug.
Is there any other people here having this issue?

[Stevie Beth Mhaol (kormat)]

Sorry, really should have included those details. I'm using ubuntu 6.06. xchat-gnome version 0.11-0ubuntu6. It is 100% reproducible on the two dapper machines i have here.

Crud. That last attachment seems to have gotten eaten. Attaching again with a less launchpad-hostile name.

[Guillaume Desmottes (cassidy)]

Could you give us a trace using a xchat-gnome with debug symbols please?
If needed you can use this package http://www.cerkinfo.be/~kujo/xchat-gnome_0.11-0ubuntu5_i386.deb

Do you have this crash with a fresh user?
What's your locales?
Did you try with C as locales?

[Stevie Beth Mhaol (kormat)]

I tried with the above linked debug xchat-gnome package, same crash, and the backtrace (attached) looks very similar. I've just tried this with a fresh user, same crash every time. My locale is LANG=en_IE.UTF-8. Trying with LANG=C made no difference.

[Stevie Beth Mhaol (kormat)]

I'm attaching the output from bug buddy too in case that's more informative, also generated from the debug xchat-gnome package.

[Guillaume Desmottes (cassidy)]

Thanks for all these backtraces Stephen. :)

Could you try to run this little test program please?

[Stevie Beth Mhaol (kormat)]

Sure:

Found the issue, here's a patch that fixes it. It's been a while since i last did gtk programming, so it may not be the cleanest way to handle this. Disabling the menu entry (and keyboard shortcut) until there is something to save would probably be best.

[Guillaume Desmottes (cassidy)]

Ahhhh i just understood than you haven't any session launched!
Sorry for noise, i was looking at the wrong line for the bug.

Thanks a lot for your patch but i don't think a error popup is useful here. I prefer to just don't do anything if there is no session (like with others functionnalities).

Fixed in the development version. The fix will be available in the next major release. Thank you for your bug report.
