Version:           unspecified (using KDE 4.7.3) 
OS:                Linux

OKULAR version: 0.13.3 (not available in the drop-down list at the moment of writing)

When I open a PDF file with okular from console and then close the app, the following message is written to the console:

okular(19795)/kdeui (kdelibs) KXMLGUIClient::~KXMLGUIClient: 0x23041b8 deleted without having been removed from the factory first. This will leak standalone popupmenus and could lead to crashes.

While this feels harmless how, this warning bothers me somewhat. Memory leaks are bad ;-)

Reproducible: Always

Steps to Reproduce:
Open a PDF file with okular (in konsole/xterm), close the app.

Actual Results:  
The message (see Details) is printed to the output.

Expected Results:  
The app should be closed "cleanly", without warnings.
