Status in “mythtv” package in Ubuntu: New

Bug description:
Binary package hint: mythtv

Dmesg output snip:
[ 1113.266797] mythfrontend.re[4016]: segfault at 0 ip 069b4006 sp bfc57020 error 4 in libmythvideo.so[68cd000+17e000]

If I try to play a m2ts file (h264 video, mlp audio) in MythVideo, I consistently get a segfault in libmythvideo.so.

Mythtv is setup with the VDPAU Normal profile, and the following filters: vdpaucolorspace=auto, vdpaustudio

Also tested without any vdpau filters.

Playback of the same file using mplayer is working (except that mplayer cannot detect the TrueHD audio).
