New crash information added by DrKonqi

okular (0.12) on KDE Platform 4.6.00 (4.6.0) "release 6" using Qt 4.7.1

- What I was doing when the application crashed:

I was clicking in Konqueror on a pdf file (same crash, if leftclicking with
direct opening or rightclicking and selecting okular in context menu). Shortly
after start, okular crashes.

I have reported that earlier.

New information is following:

- Custom settings of the application:
It seems to depend on the setting of "creation in background" in
"Einrichten->Leistung" (Preferences->performance). If set, okular crashes. This
can be reproduced.

Hope, this will help to fix it.
