I have installed Fedora 15 Gnome 3 spin, I installed plasma-desktop in addition to gnome.
All worked very good until today.
I don't know what I did to mess up all the KDE applications but the two last actions I did before it happened:
I added KDE repository - "http://apt.kde-redhat.org/apt/kde-redhat/fedora/kde.repo"
I installed KDEsvn
Now all KDE application like Kmail, KWrite, Kate, Ktorrent, Kdevelop, plasma-desktop etc
Work extremely slow, crashing and not responding.
Also if I try when login with KDE desktop instead of Gnome it unable to load I just see blue screen with mouse pointer.
I tried to remove KDEsvn and reinstall some KDE software it didn't help.
I also tried Google this problem and didn't find any thing that help me.
