totem-video-thumbnailer crashed with SIGSEGV in magazine_chain_pop_head()

[two clix]

[Impact]

A crash when seeking a h.264 file.

[Test Case]

See comment #9 on how to reproduce the bug with a short clip attached.

[Regression Potential]

Upstream released a new stable release just with this fix, so seems safe.

Confirming fixed with 1.2.4 bug fix release from Debian: http://http.debian.net/debian/pool/main/g/gst-libav1.0/gst-libav1.0_1.2.4-1.dsc

Status changed to 'Confirmed' because the bug affects multiple users.

[Gustavo Guidorizzi (gguido)]

Totem crashed when I tried to jump to another part of the video.

[Timo Aaltonen (tjaalton)]

probably https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=739579

which is fixed in 1.2.4-1

Attached test clip crashes with:

[Timo Jyrinki (timo-jyrinki)]

Confirming that gst-libav1.0 1.2.4 from Debian fixes the issue for me.

[Iain Lane (laney)]

Uploaded gst-libav to utopic-proposed/unapproved

[Iain Lane (laney)]

& trusty too

[Burt P. (pburt0)]

Somehow I was changed the status to fix released, but I can't change it back to fix committed. Anyway, it still exists in trusty. Does fix committed mean that it won't be available until 14.10?

[Thanos Kyritsis (djart)]

@Burt I've installed the package from trusty-proposed/unapproved by directly downloading it from a mirror pool, i.e. http://archive.ubuntu.com/ubuntu/pool/universe/g/gst-libav1.0/gstreamer1.0-libav_1.2.4-1_amd64.deb and the bug is indeed gone (Yay!). Hopefully, it will show up in the normal package repo as well.

[Chris J Arges (arges)]

Hello two, or anyone else affected,

Accepted gst-libav1.0 into trusty-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/gst-libav1.0/1.2.4-1~ubuntu1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Bonjour,

Merci de votre réponse mais je suis incappable d'essayer gst libav parce que mes connaissances ubuntu sont très limitées. Et donc, je ne vois pas comment procéder.

Le problème avec totem est survenu lorsque j'ai tenté de lire une video mais un problème de touchpad a démarré de nombreuses lectures simultanées. Je pense qu'il s'agit de ce jour.

cordialement.
