The exact error is this:

flynn at scienide% beep-media-player
GThread-ERROR **: file gthread-posix.c: line 188 (): error 'Resource
deadlock avoided' during 'pthread_mutex_trylock'
aborting...
Abort (core dumped)

It happens pretty early when the program is about to load the skin.

The problem was that I was mapping libc_r.so to libpthread.so. beepmp
crashes with libpthread, so I had to undo the mapping. However, it's
still true that people who linked beepmp with libpthread need to remap
the lib, e.g. 

[beep-media-player]
libpthread.so.1         libc_r.so.5
libpthread.so		libc_r.so

... and so on.

Interesting, I haven't experienced problems with KDE, at least not in
5.2, I'm waiting for 3.3 to come out to try it again (now on 5.3).

Thanks, I'll have a look.

beepmp links with libgthread and libc_r. If libc_r is mapped to
libpthread the program aborts, it works fine with libc_r.

I'll have a look at the offending code when I have some spare time.
