[MonoDevelop] Strange crash when dragging

[Dan Shryock]

I am currently experiencing a very strange crash when using Mono
Develop.  It occurs when I go to the designer view, and start to drag
a control to the form.

The message printed to the console is below:

ERROR [2008-08-27 11:41:39Z]: Could not load assembly: glade-sharp,
Version=2.12.0.0, Culture=neutral, PublicKeyToken=35e10195dab3c99f

(MonoDevelop:10208): Gdk-WARNING **: Error reading Motif target table

The program 'MonoDevelop' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 25925 error_code 3 request_code 18 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)


I have encountered a very similar problem when dragging in Banshee
before, but I can no longer recreate the problem.  Does anybody have
any ideas about the cause for this sort of problem?
