End Session Dialog's With unknown description

Sometimes when I logout I the inhibit dialog of the end-session-dialog module is shown but I only see null as the name of the program that is blocking the session ending. I have attached a screenshot that shows the problem.

When you see this problem again do this:
- close logout dialog
- open terminal
- gnome-flashback --replace
- try to logout

Post warnings/error if any.

I confirm this problem. It usually happens for me with Qt4 applications. It can be easily reproduced by opening vlc, then open the logout dialog. While the logout dialog opens, gnome-session sends a signal to applications, which causes Qt4 applications exits immediately for some reason. So there is a race condition.

Here is the output of gnome-flashback:
