today, I had the following problem:
I was editing a few photos in GIMP and after I finished with that, I
tried to close GIMP which failed. KDE offered me to terminate the
application which also didn't work.
So I opened a terminal and tried "killall -9 gimp" --> No success
Next I tried "pgrep gimp" to get the PID of the hanging process. With
the result that pgrep now also got stuck with hangup of my whole shell.
A "strace pgrep gimp" told me that pgrep actually hung up on a read on
"/proc/18294/cmdline" so I guessed that this could be my hanging GIMP
process. But even "kill -9 18294" was not able to kill the process.
So I switched over to a VT shell and logged in as root which at first
hung up the login shell, but was fixable by pressing "Ctrl + C". Even as
root I was unable to kill GIMP.
The kernel didn't actually crash. My music player continued to play
nicely and my mail client was fully usable.
I saved some log output to pastebin: http://pastebin.com/FPDvyePJ
What has been happening here? Why is it possible that I actually get

Thank you very much in advance.
