Status
------
This change has been marked as submitted.
Review request for Plasma and Solid.
Changes
-------
Submitted with commit d062d40582e00c8f34b8e0a1fd1e457d71b70ed9 by David Edmundson to \
branch Plasma/5.3.
Bugs: 347626
http://bugs.kde.org/show_bug.cgi?id=347626
Repository: libkscreen
Description
-------
GetConfigOperation stores a raw pointer to the backend in a property of
the QDBusPendingCallWatcher
BackendManager owns this backend and can delete it at will if it becomes
invalidated, leaving a dangling pointer in the watcher's property.
BUG: 347626
Diffs

Diff: https://git.reviewboard.kde.org/r/123860/diff/
Testing
-------
Never made the crash happen myself, but looking at the backtrace and the code it \
seems the a way it could have happened.
Tested behaviour as before still works.
Thanks,
David Edmundson
