KDE-Forum.org

My system crashed while I was in a KDE session, requiring fsck at reboot. Now I can't start KDE (version 3.2) with the same user account I was using at the time of the crash. :cry: I get the ksplash window, but the progress bar sticks at the second step for a while, then the splash window disappears and I get left with a blank X root window with no functions except Ctrl-Alt-Backspace working.
The last message in .xsession-errors afterwards is: "kbuildsycoca running..."
Other user accounts (root and one new account I created) can use KDE just fine, so I believe some of the KDE startup files in my home directory must be trashed. However, I tried removing the .kde directory and .kderc but that didn't help. What other files does KDE 3.2 use during the start? What's "kbuildsycoca" and what could cause it to lock up?
The OS is Fedora Core 2 Test 1 with latest updates.

Removing the files from /tmp didn't help. Running ksyscoca gives:[code:1]$ kbuildsycoca
QPixmap: Cannot create a QPixmap when no GUI is being used

Warning: kbuildsycoca is unable to register with DCOP.

[/code:1] and then nothing. It appears to be stuck in a loop using all CPU:[code:1]$ top -b -n 1

Now it works again
Many thanks!
