Clear .DocumentRevisions-V100

This program didn't help either.

I just need a way how to clear some cache/property/whatever ONCE to have a clean session 😟

Very strange. From what I've read, deleting <your home folder>/Library/Saved Application State should have done it. Were all the apps in question quit (and the associated windows closed) when you did that? If there's any doubt, open the apps again, close each window, then quit the app. Then delete the folder again.

Another long shot:

See what's in <your home folder>/Library/Containers.

Closed all apps, deleted the folder etc... tried everything.

My Containers folder is empty.

also all configuration changes on the dock (autostarts, adding program to the dock), Desktop-Wallpaper etc.. will not appear on next start

My Lion always starts up with an old recovered Session when I reboot. This is not because I'm checking the Save Application Check on shutdown (because it seems to be always the same session from Nov. 29).

How do you know the session is from Nov. 29?

Rats. You're probably going to have to contact Apple.

I don't know if or how well it works in Germany, but I've heard good things about Express Lane in the U.S.

Otherwise, AppleCare, an AppleStore, or Apple Authorized Service Provider (per the Contact button at the bottom of this page).

Please post back if they come up with a solution. I haven't seen this particular problem reported here, but someone else may stumble across it.

That's only a blind guess

Make at least two independent full backups of your startup volume. Boot from your recovery partition and launch Disk Utility. Check the SMART status of the internal drive. If it's not "Verified," replace the drive immediately. Otherwise, erase the volume and reinstall Lion. When you reboot, import your data from one of the backups.

I'm assuming you have only one HFS data partition on the drive. If you have more than one, back them all up and re-partition before reinstalling Lion.
