           Summary: zen-installer throws exception after clicking "Close"
                    button
           Product: gtk#
           Version: 2.x
          Platform: i586
        OS/Version: SLED 10
            Status: NEW
          Severity: Critical
          Priority: P5 - None
         Component: gtk-sharp
        AssignedTo: mono-bugs at lists.ximian.com

Description of Problem:
When you click the "Close" button in zen-installer after installing a package,
or in zen-remover after removing a package, you get the Exception listed below. 

Oddly enough, if you just click close without installing or removing a package,
the exception isn't thrown.

This happens in gtk-sharp2-2.8.5-0.suse101.novell (default in 1.9.0p1), but not
in gtk-sharp2-2.8.3-43.10 (default in 1.2.6).


Steps to reproduce the problem:
1. Run zen-installer in a console on SLED 10 SP1 i586
2. Install kdebase3-NLD
3. After installation, click "Close"
4. Notice the exception thrown as listed below.
