Git commit d062d40582e00c8f34b8e0a1fd1e457d71b70ed9 by David Edmundson.

Handle backend being deleted during GetConfigOperation

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.

Comment 5 Jan Swaelens 2015-06-04 06:42:07 UTC 
Hello,

Is this fix released already, just updated to the latest plasma version but still having the crash. In addition it seems some processes just take of starting to consume CPU making the system unresponsive.

Thanks
