Maybe this could be useful to anybody. I selected second option "Use existing KDE 4 setting and replace current KDE 3 settings" but had issues in one of my computers (no issues in another one).
Kaboom could not remove some files in ~/.kde/share/apps/ktorrent/tor5/cache/ that cointained spanish/galician accents for condification problems. To be more descriptive, first I got some alerts telling me that those files could not be found and after that I got alerts notifing that some directories could not be removed because of were not empty. PS: I had previously some problems in Dolphin with filename condification so that could be just me and not a problem with Kaboom. -- Ramon Antonio Parada Skype: ramon.parada Spain: +34 651 948819 US: +1 (310) 651-8072 http://ramonantonio.net/
