Mixxx 1.8.0 beta2-pre Segfault on exit

A few segfaults have been fixed since this bug was reported. Mind trying again with current trunk and see if this problem still happens to you?

Still happens.
Tested with Mixxx 1.8.0~beta2-pre "(bzr r2400; built on: May 19 2010 @ 11:49:48; flags: hifieq vinylcontrol midiscript optimize=1 qdebug)

jus, can you get a back-trace by issuing the command:

at the gdb prompt after the crash? Thanks.
