Skype 2.2.0.25 keeps switching off

It crashed for everyone. Apparently on Linux you keep getting Aborted on the console upon logging in. What fixes the problem is removing shared.xml from settings directory. Thus on Ubuntu it's:

rm ~/.Skype/shared.xml

BTW. bit off topic here, but just for the sake of it

On Windows remove:

c:\Documents and Settings\*user*\Application Data\Skype\shared.xml

On OSX:

rm ~/Library/Application\ Support/Skype/shared.xml

Update: There is official acknowledgment of the issue from Skype.

Try deleting shared.xml file in your home directory ~/.Skype/shared.xml

This command in the terminal will remove it rm ~/.Skype/shared.xml

I had the same Problem after the recent unity-update. Removing $HOME/.Skype/shared.xml helps it.
