MonoDevelop crashes all the time

After acting oddly for a week, MD just started crashing all the time without the typical window, as if it was a clean quit (except the files are not saves so it is not a mis-bound key).

I cannot identify the cause of this and even after re-installing unity and re-synching the project it behaves the same way.

Has anyone found a solution to this ?

I’ve got the exact same problem with latest Unity (developer preview) ; Monodevelop can’t stop freezing everytime or so, and I need to KILL the Monodevelop process everytime. This machine runs WinXP SP3 .
On the other machine however, Win 7 x64, there is absolutely no crashing.
Would it be due to GTK+ ?

I recently installed GTK# 2.12.9 and also the 2.12.20 version (I did it to try out two new MD 3.0 and Xamarin Studio 4.0 along with my Uniy 3.5 - which didnt work very well). I reverted back to MD 2.8, but forgot to uninstall the new GTK#'s. After that I had my MD 2.8 crashing about 20+ times a day.

Long story short, I uninstalled ALL GTK in my system, and now it’s stable again with MD 2.8.

Hope it helps.
