NetBSD 2.0.2 running lyx built with qt errored at exit with:
lyx: Error detected by libpthread: Destroying locked mutex.
Detected by file
"/home/builds/ab/netbsd-2-0-2-RELEASE/src/lib/libpthread/pthread_mutex.c",
line 135, function "pthread_mutex_destroy".
See pthread(3) for information.
Abort trap (core dumped)
This is from NetBSD. But is caused by bug in LyX (I think) or qt. This is
pkgsrc package lyx-qt-1.3.5nb2.

Is this "Destroying locked mutex" something that can be (or is) fixed in
LyX? Or is this a QT3 issue?
