Comment 6 for bug 294084

i think this is a duplicate to:
https://bugs.launchpad.net/ubuntu/+source/desktop-effects/+bug/88152

and all other bugs in its (88152) duplicate list.

btw, i use desktop-effects on the first user i log into.

this system lock down happens after fast switching between
already logged in users that are using the system for some time
(some times days)

we switch allot and then it hangs.
