Thanks for the bug report! Do I understand correctly that Dolphin was in the background and you only zoomed in Okular when Dolphin crashed?
Comment 2 Jeroen van Meeuwen (Kolab Systems) 2012-08-24 16:19:47 UTC
Resetting assignee to default as per bug #305719
Comment 3 George 2012-08-24 19:29:49 UTC
Yes that's correct
