First preview for Mono 2.0 is released with new Monodevelop version (in alpha state). I did not expect stable work from this release, but was very surprised.
From first look, there was only one annoying bug that could be easily fixed. So, during start up I got window with following error:
Add-in error ():
GLib.GException: Unrecognized image file format

After a bit of tweaking I found that Gettext Translation Support addin gives this nasty error. By disabling it I resolved bug issue.
