I've been trying to get amaroK 1.4 up and running, and have a consistent crash problem when I try to play .m4a files.  When I start a playlist, amaroK will play the first .m4a file just fine, but when I try to switch it to another track (any file format), or when it finishes that track and attempts to continue to the next one, the application crashes.  It plays mp3s and wavs fine, I haven't tried any other formats.  I've been compiling amaroK from source with the xine engine and mpeg4ip installed (I've tried both 1.4.1 and 1.4.0a with the same results).  I tried 1.3 from apt, but that version just crashes as soon as I try to play a .m4a file.  I obtained a backtrace, pasted below.  Please let me know if there's any other information I should be posting, or if there's another place I should be looking for help.
