I'm afraid the app is very complex with many moving parts. I might be able to tell you what is going on if it survived long enough to spit out a log.
I did miss this relevant line from the logcat log:
| F/libc | (20971): Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1), thread 21413 (FP_AudioCallbac) |
I would assume from the name that this points to an audio problem (in the callback service).
