Do you have gtk-qt-engine also installed?

[Alan Boudreault (aboudreault)]

I confirm this bug. Yes, i have gtk-qt-engine also installed.

[Petar Forai (pfo)]

Yes, gtk-qt-engine 0.8-1ubuntu2

[Michael Mikowski (kfocus)]

Confirmed in kde4.1.1. I had gtk-qt-engine-kde4 and gtk-qt-engine installed.

Purging gtk-qt-engine removed the conflict. Gimp and Firefox then started as expected.

[Jonathan Thomas (echidnaman)]

The gtk-qt-engine-kde4 package in the KDE4 ppa just needs a conflicts/replace on the gtk-qt-engine package.

[Jonathan Thomas (echidnaman)]

This should be fixed in Intrepid now that gtk-qt-engine-kde4 was transitioned to gtk-qt-engine.
