Review request for Plasma and Alexander Mezin.


Repository: plasma-desktop


Description
-------

This is an attempt to fix the crash reported at https://bugs.kde.org/show_bug.cgi?id=358190.
Yet, I am neither familiar with the code nor with using XCB. So I cannot judge if this is only a workaround or a proper fix.


Diffs

Testing
-------

Solves the crashes for me.


Thanks,

Andreas Cord-Landwehr
