[PyQt] PyQt5.4 stuck on QtQuick.Dialogs

[Fabien Castan]

Hi,
I still have the problem with the latest snapshot
"PyQt-gpl-5.4.1-snapshot-55f521ae431b".

#0  pthread_cond_wait@@GLIBC_2.3.2 () at
../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S:185
#1  0x00007ffff01f9b03 in QWaitCondition::wait(QMutex*, unsigned long) ()
from /opt/Qt5.4/5.4/gcc_64/lib/libQt5Core.so.5
