Also see bug #362137

Since we're not getting debug symbols from Archlinux (easily), please install the debug packages for QtGui & QtQuick, recause the crash and provide an updated backtrace (with symbols & values), but the same segfault in two clients strongly suggests it's QtQuick shooting itself.

As bug 362148 has been marked as a duplicate of this bug, I'm posting here:

I installed qt-debug packages from the respective repo (https://wiki.archlinux.org/index.php/Unofficial_user_repositories#qt-debug) and managed to crash plasmashell another time. Please find the gdb log attached.
