Hi,
I'm sorry for possibly false alarming and vague description. I'll supply
more info as we go.
Many times now I see application crash on exit. It's in different places
but it seems that QMetaType::destroy is a common pattern there.
On the start I have a message:
>> QObject::connect: Cannot queue arguments of type 'QRectF'
and on exit I got:
X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 18 (X_ChangeProperty)
Resource id in failed request: 0x0
Serial number of failed request: 402249
Current serial number in output stream: 402313
Segmentation fault (core dumped)

Any ideas or test I should run to clarify the situation?
