Description cedric 2015-11-01 10:05:25 UTC
Plasmashell occur to freeze sometimes, I don't know which event trigger the freeze, it looks like a deadlock in QtQuick.
looks not a duplicate of this bug https://bugs.kde.org/show_bug.cgi?id=353292 according the stack trace I have.
I can try to get more informations the next time I get the freeze, just ask me what you need.
