[Pkg-mono-devel] Problems with mono 1.1.9 and MWF

[Alessio Frusciante]

Hi,
I installed the preview packages for mono 1.1.9 from meebey's
repository, but I'm having problems with System.Windows.Forms. Every
time I run an application using DateTimePicker class I get an error like
this:

Unhandled Exception: System.NullReferenceException: Object reference not

Looking around I found this thread:

http://lists.ximian.com/pipermail/mono-winforms-list/2005-August/001949.html

could it be related?
(btw. I'm using debian unstable and I didn't have libgdiplus installed,
but installing libgdiplus 1.1.8-2 made no difference).

Ciao
