[Feisty]Openoffice writer freezes when opening a file

The following problem occured on a Feisty i386 machine with all updates until Oct. 30th: When I tried to open an Openoffice Writer file from my desktop clicking on it, OO opened it, but then froze: I still could see the content of the file, but scrolling, clicking or performing any action did not work. I only could minimize the window, if I closed it, I had to "Force Quit".

Running ooffice from the console 'ooffice file.odt', most files were opened and I could use them. But still with some of them, writer froze. I could also open most files by opening it from the file => open dialogue.
Running ooffice from the console freezing didn't give an error.

This started with an update maybe 2 months ago, uninstalling and reinstalling openoffice did not solve the problem, it was present for all users of this machine. But after deleting the .openoffice.org2 directory in the home directories the problem didn't occur any more.
