Hi there,

since I have upgraded to 4.99.36 I am experiencing a curious bug (that 
never happened before) while trying to display a (mere) window under the 
Qt4 toolkit:

Error detected by libpthread: Invalid mutex.
Detected by file "/usr/src/lib/libpthread/pthread_mutex2.c", line 223, 
function "pthread__mutex_lock_slow".
See pthread(3) for information.
QMutex::lock: mutex lock failure: Invalid argument

I am wondering if this is a (transitory) bug in libpthread (it does not 
spring up every time, btw), or shall I recompile Qt4 because the API has 
somehow been modified?
