Description of Problem:

When adding a custom menu to Xamarin Studio, which opens up a Dialog, repeatedly opening/closing the dialog will eventually cause Xamarin Studio to crash.

Steps to reproduce the problem:
1. Download the attached "CustomMenuWithDialog.zip" add-in
2. Extract and open with Xamarin Studio (requires Xamarin Studio Add-in Maker)
3. Debug the project
4. In the debug Xamarin Studio instance select the "Test Menu > Custom Dialog" option
5. Dismiss the dialog by clicking the "Cancel" button
6. Repeat until Xamarin Studio crashes (may take several dozen iterations)

Actual Results:

Xamarin Studio crashes unexpectedly

Expected Results:

Xamarin Studio remains open despite repeatedly opening/closing a custom Dialog

How often does this happen? 

Issue is reproducible after dozens of opens/closes every time, though the number of times you have to open/close varies.

Additional Information:

Sometimes, when you click the "Cancel" button, all of the controls in the dialog disappear, but the dialog doesn't actually close.
