Comment 8 for bug 199145

running "sudo update-desktop-database -v 2>&1|grep invalid" resulted in no output, so I am not sure if this is the problem (at least for me). I will just wait for updated debs since I am not knowledgeable enough to apply patches and build packages for myself.

If there's any thing someone like a typical end-user can do to help, I would be willing to do it.
