I've installed the RPMs for Mono and MonoDevelop from the F9 repos to try to get some of the improvements in MonoDevelop (since F8 is still on Beta 2 built for F7). I've done it before to get slightly newer versions of Mono, but at the moment MonoDevelop doesn't want to recognise any addins.
The app starts and you can edit files, but when it first starts then there is an error message of "the following addins couldn't be started". Each one has a blank line and is caused by a null argument exception.
[ibboard@AnkhMorpork .config]$ rpm -qa|grep mono
Console output from startup is attached.
Is this a known issue (at which point why is it in the repos, even if it is Alpha?) or is this something odd with running it on F8? I've tried with a clean .config/MonoDevelop folder and it doesn't seem to make a difference.
