Notice, ->get_capabilities is bogus (?), it doesn't resolve to symbol.

Reproducible: Didn't try

Good that you posted the backtrace info. Please add an explanation of what you were doing when the segfault occurred, and see if it is reproducible by doing it again.

[Comment 2 Alexey Dobriyan 2010-01-13 06:18:36 UTC]

Nothing special I was doing.
Allegedly, dolphin was previewing some video files shortly before.

coredump, however, was in directory without any video files.

And it didn't happened again so far.

[Comment 3 Samuli Suominen (RETIRED) 2010-02-24 21:40:20 UTC]

Hmm, try xine-lib-1.1.18 and phonon-4.3.80-r1.

[Comment 4 Andreas K. Hüttel 2010-08-18 20:24:01 UTC]

any news?

[Comment 5 Andreas K. Hüttel 2010-11-12 23:35:12 UTC]

No response for longtime...
