Comment 2 for bug 184001

I was using KDE3 from kubuntu packages (kubuntu Gutsy), and obviously links were opened by konqueror itself, as usual. This started to malfunction when I installed KDE4 following the instructions linked above.

I don't know if these kde4 packages were directly responsible for this behavior, but I don't remember tweaking anything in the configuration, so I assumed they were.

In any case, the fix is simple enough to not deserve further attention.
