Due integration into kde workflow I shut down the own bugtracker system. If you want to file bugs or feature request you have to use now the bugtracker from kde itself: https://bugs.kde.org/enter_bug.cgi?product=kdesvn.
For that you require a login on this site, but it’s ok I think. I saw it on the old bugtracker, open commits to bugtracking system is sometimes horrible for the admins due spammers.
You make take a look into existing bugs for kdesvn before posting a new one.
