I have a weird problem: after installing gv from Fedora Extras, evince is no longer able to open pdf or ps files. Not only is it not the default application for these file types any more, but when I explicitly type 'evince file.pdf' I get a messages saying: Unable to open document Unhandled MIME type: 'application/x-extension-pdf' Of course I tried the usual solutions, like uninstalling gv and reinstalling evince, but no success so far. Created a new user, same problem, so it must be in the system settings, not in some user preference. I'm almost completely certain that installing gv caused the problem since it was the only thing I did as root on this machine yesterday. Does anyone have an idea how to solve this problem (preferably without reinstalling Fedora). Oh, for completeness: FC4, X86_64, fully updated. David Jansen
