[mythtv-users] Mythmusic: segmentation fault at line 809 in audio/audioconvert.cpp

[Jan Ceuleers]

Hi

I purchased an album on iTunes and wanted to play it using mythmusic.
Unfortunately this results in a segmentation fault:

Program received SIGSEGV, Segmentation fault:
[Switching to Thread 0x7ffefb7fe700 (LWP 9223)]
0x00007ffff5ed77cc in _InterleaveSample<int> (out=0x38d1340, in=0x0,
channels=33, frames=1024, inp=0x7fff04015340) at audio/audioconvert.cpp:809
809     audio/audioconvert.cpp: No such file or directory.

I ran the frontend under gdb as per the instructions at [1]. I have
posted the resulting gdb.txt file at [2], and the log file generated by
the frontend (using -v all,norefcount) at [3].

Steps to reproduce (on my system):

1. Start the frontend
2. Go to mythmusic
3. Crash

This is the case because I previously selected the new album and
selected Replace Tracks. So unfortunately the crash happens immediately
when I enter mythmusic, but from the gdb.txt file it seems to be related
to an attempt at playing back the first file.

These are .m4a files. I have many more of them and they generally play
OK in mythmusic. These particular files also play OK in Rhythmbox.

Two questions:

1. Will this do as a bug report? Would you like me to open a report in
the tracker?

2. Can you help me to revive mythmusic on this frontend, since it now
crashes immediately, i.e. before I have a chance to navigate away from
the offending file(s)?

Thanks, Jan
