[Bug 298601] Re: Firefox cannot start: Cannot mix incompatible Qt libraries

[Jon Anderson]

Are you running KDE nightlies? I had this error because the nightly KDE
messed up my Qt config. To fix this, you need to (re)move your
Trolltech.conf file so a new one can be built, like the KDE bug report
says:

$ mv ~/.config/Trolltech.conf ~/Desktop/Trolltech-broken.conf

Then run your Qt application. If you want to see what happened:

$ diff ~/Desktop/Trolltech-broken.conf ~/.config/Trolltech.conf
