Package: libavcodec52
Version: 4:0.6.2-4
Severity: important
I'm running an x86-64 Debian sid with libavcodec52 package version 4:0.6.2-4.
During playback of many (but not all) wmv files that I have in players such as
vlc, totem and mplayer, I experience a crash in libavcodec.so immediately or
shortly after the start of playback.
Here's a sample stack trace from vlc:
Program received signal SIGSEGV, Segmentation fault.
