Review request for Dolphin.


Repository: kde-baseapps


Description
-------

If dolphin is launched with the information pane on and set to display preview PixmapViewer::paintEvents seems called three times before any pixmap is set. Each time the above warning message is output.
This does not happen if the preview feature is off when dolphin starts or if it is toggled after launch.

-----

Diff: https://git.reviewboard.kde.org/r/119553/diff/


Testing
-------

Verfied that warings are gone and a information pane works as epected. 


Thanks,

Michael Reeves
