abrt 1.0.1 detected a crash.

Comment: I did nothing specia. I was using nautilus and after I created new folder (.fonts in home folder) with it, as it got confused with that folder. Folder didn't disappear immediately but first it appeared as Untiteled folder, then with it's real name. I then check and unchecked 'Show Hidden Files' option. After that it disappeared and Automatic Bug Reporting Tool shown up.
