When viewing the help in monodevelop, if you select a node in the help tree
and attempt to drag it monodevelop will crash. This is bad because it is
easy to accidentally drag a help node resulting in a loss of all unsaved data.

Steps to reproduce the problem:
1. Open monodevelop 
2. Make sure the Help pane is visible by selecting View|Help
3. Click and drag attempt to drag around a few help nodes
4. After a few click and drags the program will crash

Actual Results:

Crash resulting in monodevelop terminating.

Expected Results:

No crash.

How often does this happen? 

Always.

Additional Information:

I am running Ubuntu Linux 6.06 and the latest version of monodevelop
compiled from the sources at svn://svn.myrealbox.com/source/trunk/monodevelop

I can't reproduce this problem. Help nodes can't be dragged. Can you
provide a more detailed description of the steps you follow to get the
crash?
