gtkpod segfaults

[Lance Poore]

Binary package hint: gtkpod

##Edgy Possible Bug:

I get gtkpod segaults that I did not get with "dapper". The segfaults happen when you run gtkpod with an ipod already mounted. If you unmount the device after it has been plugged in, then sometimes, not all the time, gtkpod might work without segfaulting. It's just work when it wants to kind of deal as long as you don't already have your ipod mounted. If you leave the ipod mounted and turn off the gtkpod option to automatically mount and unmount your ipod, then you still get a segfault.. The only way to get it to ever work, is to plug it in, unmount, and load gtkpod (with the option to let gtkpod mount / unmount the device). When you get done using it then it unmounts, but you still need to "eject ipod" to prevent your ipod from being recognized as a different block device the next time you plug it in.

I also get a segfault when I run gtkpod.

lontra@lontra-laptop:~$ gtkpod
Segmentation fault (core dumped)

lontra@lontra-laptop:~$ apt-cache policy gtkpod
gtkpod:
  Installed: (none)
  Candidate: 0.99.4-1ubuntu1
  Version table:
     0.99.4-1ubuntu1 0
        500 http://ca.archive.ubuntu.com edgy/universe Packages

...strange that it says Installed: (none)...maybe that's another bug? It's definitely installed.

This is also on Edgy

[ChrisDesjardins (cddesjardins)]

The work around described above works for me as well. So I guess I'm just verifying this bug.

Thanks for your bug. What is the gtkpod path according to "which gtkpod"? Could you get a backtrace with gdb?
- gdb gtkpod
(gdb) run
... crash
(gdb) thread apply all bt

and copy that to a comment

[Lance Poore (lp-7413)]

I'm sorry sebastian, i have stopped testing edgy, and
returned to dapper, I'm sorry it would be impossible
to do all of that without reinstalling edgy. Have you
tried it? did you have any problems? please let me
know! thanks

I attached a apport report in bug #62724, with a stack trace.

[Mark Stralka (mstralka)]

I experienced the same problem with Edgy. I uninstalled and then reinstalled gtkpod. Problem went away.

[Mark Stralka (mstralka)]

Correction - I am having the same problem again. Uninstalling/reinstalling gtkpod worked before but is not working now.

[Mark Stralka (mstralka)]

Here's the problem report

[Lance Poore (lp-7413)]

I would just like to confirm that gtkpod is no longer crashing in edgy. The bugs must have been fixed. thanks guys!

[ChrisDesjardins (cddesjardins)]

gtkpod is still segfaulting on my machine so this bug report should not be
closed.

In my case it seems that gtkpod crashed only when the ipod is plugged in. If the ipod is ejected then gtkpod loads and after mounting it reads the ipod. Synchronising files does not work but gtkpod shows the available disk space on the ipod.

[Kim Chee Leong (kc.leong)]

Gtkpod (0.99.4-1ubuntu1) works fine in Edgy Eft, no more segfaults for me.
