Unable to change preferences

Confirmed. I can change what I want in the preferences, but the settings aren't remembered and revert to their previous values. So far I tested skin, UI language and date format.

Now I was able to change the languages at least after a while. I had to save the preferences several times. Everyting still not getting saved - still acting strangely.

We recently upgraded our memcached from version 1.2.2 to version 1.4.3. Apparently that didn't agree too well, and user objects and whatever were not purged when they should. So your user preferences *were* actually saved, just not used (OUCH!). We are now back to using memcached 1.2.2, which we know gives the occasional error, but at least works as it should.

Sorry for the inconvenience.
