encoded urls in KUrlNavigator

[Sebastian Trüg]

For the nepomuk kio slave I wanted to use URIs as fields and values in 
queries. However, since URIs contain slashes I need to encode them. The 
result looks like this:

nepomuksearch:/<http%253A%252F%252Fwww.semanticdesktop.org%252Fontologies%252F2007%252F08%252F15%252Fnao%2523hasTag>:<tags%253A%252FNepomuk>

(the query lang uses < > to mark URIs)

Now the problem is that this results in an endless loop as 
KUrlNavigator::setUrl duplicates each %25 to %2525. I cannot determine why. 
But it seems to happen in the KUrl constructor.

However, Konqueror has no problem here, probably because it does not use 
KUrlNavigator.

I do not have enough inside here, so could someone please have a look. Dolphin 
not being able to handle encoded URLs entered by the user is not that a big 
deal, but an endless loop is.

Cheers,
Sebastian
