Description of problem:
Browsing my ${HOME} no matter in icon or tree view, I accidentally enlarged 
the fonts and icons with a mouse click or a couple clicks on the Main 
Toolbar's "Enlarge Font". The konqueror spectacularly crashed with SIGABRT.

Version-Release number of selected component (if applicable):
3.5.6-0.1.fc6

How reproducible:
100% just click the magnifying glass on the Main Toolbar 
Ctrl++ is blocked and doesn't work in the file browser (luckily).



Steps to Reproduce:
1. Click "Enlarge Font"
2.
3.
  
Actual results:
SIGABRT crash

Expected results:
Don't allow this action

Additional info: To recover you need to delete
.kde/share/config/konqiconviewrc and .kde/share/config/konqlistviewrc
