Can you please provide us with such an mjpeg file so that we can test if the problem still exists in FFmpeg 0.6? The backtrace you've posted unfortunately doesn't show immediately the problem, we'd therefore need a proper testcase. Without that, there is little that we can do for you. -- Gruesse/greetings, Reinhard Tartler, KeyID 945348A4 -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

You may want to check your jpeg file for errors with some of the jpeg tools available in the archive. I've never had an issue with jpeg files myself during my tests.

Bug#609271: segfault when loading some jpeg files
Package: forked-daapd
Version: 0.12~git0.11-125-gca72ee5-3
Severity: important
Hi,
forked-daapd segfaults when it tries to index some jpegs in my library.
A full backtrace is attached (using ffmpeg-dbg and forked-daapd rebuilt
unstriped).
Seems to be something from inside ffmpeg here :(
Regards
Evgeni
PS: this is my first forked-daapd installation, never used it before.
