Description of problem: Upon accessing the Mail Notification preferences, I get a dialog that says: A fatal error has occurred in Mail Notification The default configuration has not been installed properly. Please check your Mail Notification installation. Version-Release number of selected component (if applicable): 5.2-3.fc9 Additional info: I upgraded this system to Fedora 9 Preview from Fedora 8. Perhaps this is the result of some crufty configuration file?
There was several such bugs already. It seems that it is related to the changes of a way how mail-notifications deals with Gnome. As a result, an old stuff (perhaps not removed completely at update time) prevents the new instance of mail-notifications to run properly. The probably work-around is to remove mail-notofications from the panel at all, and add then again. Make sure that there are no more than 1 instances in System-->Preferences-->Personal-->Sessions . Please, report if it will not help you.
Note: there was a bug in the gconf scriptles in %postun in the past that could cause this problems. But I think I fixed that in F7 (or even earlier). Maybe I did something wrong?
Hmmm... Where exactly? BTW, there is no "if [$1 == "0"] ..." tests in %postun -- perhaps it is related here?..
I have removed *all* instances of mail-notification from Sessions and ensured the process isn't running. I still get the error message when attempting to access the Mail Notification preferences.
Do you use mail-notofication-evolution-plugin as well? I've compiled the new upstream release 5.3 (has appeared yesterday), try to update to it (and evolution plugin if needed): http://koji.fedoraproject.org/packages/mail-notification/5.3/1.fc9/x86_64/
The 5.3 packages appear to fix the problem.
