Looks like a mono issue, but it may be video driver(GDI).
Try a new video driver.

cheers, Paul

This is a bug in Mono. You can follow it here:

I don't know, I have tried the few workarounds and patches suggested, but to no avail (the error has some significant differences aside of the first line).
On top of that, I found that this only happens when I have my main database open.
If none is opened, or if I try with a dummy one, everything is fine.
