thumbnailer crashes on unfinished avi's or .oggs

crash report

If somebody forwards this, the backtrace from https://launchpad.net/distros/ubuntu/+source/totem/+bug/67741/comments/2 should be forwarded, it's a bit more complete.

The same thing happens with corrupted .ogg files.

I started ripping a CD using Sound Juicer with the "Ogg Vorbis, CD quality (Lossy)" profile. While this was going on, I navigated to the directory where Sound Juicer was placing the new .ogg files and Totem's thumbnailer crashed on the file that Sound Juicer was in the process of ripping. (When Sound Juicer would move to the next song, a new crash would often be triggered as long as Nautilus was left open at that folder.)

Another similar crash while creating ogg files with sound juicer.

Similar crash with .mp4 files

Here's one from an AVI. I can't find debug symbols for totem-video-thumbnailer, if someone wants to tell me where I can get them I'll reproduce the crash.

dguido: your backtrace is a different issue, please file a separate bug report about it.
Tan Kah Ping: Same goes for you.

me2: your crash dump is from gaim not totem thumbnailer.

My totem-video-thumbnailer crashed twice while downloading "FSF_moglen_appeal.ogg" from archive.org at a slow rate. Please, let me know if my crash report is needed (I'm not uploading it because it seams that there's already enough crashes reported).

same issue here, totem-video-thumbnailer crashed on an AVI file via nautilus.

one more :)

Also crashes when generating thumbnails for .vobs which are on a DVD (Feisty).

Martin, your crash is a xine-lib one, probably not the same problem than the one described on the bug your are commenting

I have a crash that may be similar or not.
I'm trying to post the .crash.tar.gz file (10 mb)

ubuntu 6.10, new user from 6.06

This crash happens when copying .avi's to a flashdrive.

It looks like the crash is actually occurring in gmain.c in libglib2.0-0 during a call to g_main_context_check(GMainContext* context, gint max_priority, GPollFD* fds, gint n_fds). This is either a set of bad args being passed or ??checking a NULL context??. If I could find out what+where this was being called from before the crash it would be helpful. My system is not very quick with debuggers so maybe I will try to code in a watch, just have to go through the thumb-nailer code looking for calls to g_main_context_check, check() or something. I am somewhat new at dealing with this kind of debugging so any tips are appreciated.

The crash is weird, not sure of what would be the way to debug it. Maybe you could open a bug upstream and ask their opinion, they know the code

Yeah, that is the next step, but I wanted to find out what code was actually causing the crash so that I know who/what project to file the bug with. Why bother glib people with something that is gnome-totem territory? Besides, I think I have a pretty good idea of whats happening here. It looks like the thumb-nailer is causing the crash while trying to open an already allocated resource. Maybe trying to open a part of a file that has changed or is currently being written. This shouldn't happen really and its specific to playable media (video/audio) as far as I can tell. I haven't tried to reproduce this bug with a media file that was incomplete but not being written to. Sorry for the theory with no support. I will get back with some more concrete info asap.

Funny thing... I tried to reproduce this crash from the command line with /usr/bin/totem-video-thumbnailer -s 100x100 incomplete-and-being-created.avi thumbnail.png and it worked fine, so I start nautilus and the files are thumbnailed with no problem, so i guess I can no longer be involved in this discussion since I cannot reproduce the bug anymore. I am using all the same packages but it is just gone. Strange.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Thanks in advance.

I'm sorry, I'm not sure. I haven't intensely used Ubuntu for quite
some time to be able to run into this issue again.

Not used Ubuntu in about 8 months now. So can't say.

I'm still using Ubuntu. And, although I don't know quite when it stopped, this bug no longer happens with me on the later releases.

ok, thanks for the feedback, closing this report then.
