Description (last modified by mf2k (Frank Schima))
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.)

We'd have to find out what beat this function to locking the mutex.
http://www.jp.kde.org/~ichi/qt/qmutex.html#lock
I'd report it to KDE, they know their software better than we do.

Can you post a link to the report in the KDE bug tracker?
comment:7 follow-up: 9 Changed 13 years ago by ak.ml@…
I had the same issue, and I think I solved it by launching kdeinit.app as it was suggested after each kde install (disappeared at r59663).
open /Applications/MacPorts/KDE4/kdeinit4.app
But first you might consider cleaning the KDE cache and maybe the temporary KDE directory. Looking at the stack trace and at my hang files, I think the icon cache might be the cause here. For the paths:
kde4-config --path cache kde4-config --path tmp

Thanks a lot! Launching kdeinit4.app solved the problem for me.

Replying to ak.ml@…:

You are right, instead this line should have been removed from that user message:
ui_msg "# 'sudo chown -R \$USER ~/Library/Preferences/KDE' "
since that directory shouldn't have non-$USER permissions anymore (see https://bugs.kde.org/show_bug.cgi?id=233892 and http://trac.macports.org/ticket/26982 ).
comment:11 Changed 13 years ago by macports@…
I'll try to submit a patch for this, but in the mean time:
This is because KDebug is not re-entrant safe, but when you first log a message to the debug output, it does some work which in turn causes debug messages to be written. At this point it deadlocks.
One (but not necessarily the correct) solution to this is to make KDebugPrivate::mutex recursive, by modifying the KDebugPrivate constructor (kdecore/io/kdebug.cpp:220) to construct it passing in QMutex::Recursive as a parameter.

Is this still a problem with 4.8.2?
comment:14 Changed 12 years ago by jgosmann (Jan Gosmann)
As stated before the problem was solved for me by starting kdeinit4.app and right now (with KDE 4.8.3_2) I can still start KDE applications.

Sorry, I messed up the gdb output. Here it is again properly formatted:
