Summary0000128: Crash when quitting r4823
DescriptionWhen i closed the QET window by the [x] window frame button, i got this crash caught by running it in debug from qtcreator. Screenshot attached.
I believe - but am not 100% sure - i did not edit anything before last save.

I believe it is r4823 as svn up did not download anything, but said anyway it is r4824 as it report latest version in another branch
TagsNo tags attached.

Backport upstream change to fix crashes on exit in some applications

+Description: make the bearer QFactoryLoader a member variable, not a static
+ Because it was a function-level static, the QFactoryLoader was getting
+ destroyed out-of-sync with the bearer thread stopping. Under normal
+ conditions, the thread stopped first (~QApplication / ~QCoreApplication
+ via qAddPostRoutine), and the static got destroyed when the process
+ exited. However, if QApplication leaked or if the destruction order is
+ wonky (as seen in PyQt5), the thread could still be running when the
+ plugins were already unloaded.
+ .
+ With the loader a member variable, it gets destroyed when the thread
+ stops.
+Origin: upstream,
QT bug 1?
