segfault when exiting mocp client with Q

Hello, mocp works ok for me but I get a crash on exit from client (music continues playing).

$ uname -a
Linux localhost 2.6.39.3 #1 SMP PREEMPT Mon Jul 11 01:53:25 UTC 2011 x86_64 AMD Athlon(tm) 64 X2 Dual Core Processor 3600+ AuthenticAMD GNU/Linux

AgiliaLinux 8.0 RC1 64bit; tested with mocp 2.5.0-alpha (pre-packaged) and 2.4.4 (from source).
I just installed it, so no config.

$ mocp -D

Any ideas?

I installed revision 2362, and behaviour is just the same :( Here is the mocp_client_log, maybe relevant:

After a long investigation we were unable to find a definite
cause for this problem. One possible cause may have been
the existence of multiple copies of some system libraries
on his system. After reinstalling his distribution on a new
machine the problem disappeared, so it was probably caused
by something unique to that previous install but is likely
to remain forever unsolved.
