KDE programs not starting (KDE 4.7.0)

[jgosmann (Jan Gosmann)]

It seems that not even a single KDE program is starting. gdb reveals that they are waiting for a semaphore or mutex:

I have KDE 4.7.0 installed.

I am not completely sure whether this is a MacPorts problem or whether I should report this problem in the KDE bug tracker.

If you need more information I, tell me and I will try to provide it. (But I won't be able to do so until next week.)
