[MonoDevelop] Crash when creating or renaming folders

[Glenn Allen]

Hi all,

I keep getting a randomish crash when creating or renaming folders in
the solution tab.  I haven't had the time to debug it or try to write a
patch, but would greatly appreciate it if someone would take a look at
it.  

Stacktrace:
