i didnt have all the debuginfo packages installed. I installed some (but
not all yet), here's an updated backtrace:

(gdb) bt
#0 0xffffe410 in __kernel_vsyscall ()
#1 0x4a2539e1 in __lll_mutex_unlock_wake () from /lib/libpthread.so.0
#2 0x4a2506f9 in _L_mutex_unlock_99 () from /lib/libpthread.so.0
#3 0x4a250370 in __pthread_mutex_unlock_usercnt () from /lib/libpthread.so.0
#4 0x4a2506f0 in pthread_mutex_unlock () from /lib/libpthread.so.0
#5 0xb79fce5a in QWidget::setUpdatesEnabled () from /usr/lib/libxine.so.1
#6 0xb7a4b90b in dvd_plugin_free_buffer (buf=0xb0745470) at input_dvd.c:570
#7 0xb7a030a2 in QWidget::setUpdatesEnabled () from /usr/lib/libxine.so.1
#8 0x4a24d2db in start_thread () from /lib/libpthread.so.0
#9 0x4a05820e in clone () from /lib/libc.so.6

at least the dvd_plugin_free_buffer() call has been resolved now. (I'll
hunt for the other debuginfo packages too.)

which thread would be the most interesting to you - 9324?
