[Mono-list] ListView.cs bugs

[Chris Bacon]

Hi,

I've just updated to SVN revision 41147 and now when I try to run this
example (which creates a form with a tabcontrol with 2 pages, one with a
label, the other with a listview) I get the following error:

** ERROR **: Unmanaged code called delegate of type
System.Drawing.GDIPlus/GdiPlusStreamHelper.StreamSizeImpl which was
already garbage collected.
See http://www.go-mono.com/delegate.html for an explanation and ways to
fix this.

before even a window has been created

Any ideas why?

Thanks
Chris
