FileChooserDialog for saving behaving badly on Windows but fine on Linux.

[Nev Delap <nev delap intelestream net>]

Hi there,

My application is fine in Linux running under Mono 2.6.7, but in Windows
running in Mono 2.6.4 or Mono 2.8 I get the trace output and crash below
when using the file chooser dialog for saving.

It is when I do a save as, and type a filename and the dialog selects one of
the existing file names of the same type as I'm typing, so the name selected
is different from the name entered - resulting in a crash. If there is no
existing file of the same type or I type in a new name and manually
Ctrl+Click twice in the list to unselect the name that the dialog has
selected as I was typing, and click to put the focus back in the text entry,
then it wont crash.

This Windows install is a completely clean XP install with Windows Installer
3.1, Windows Imaging Component, .Net Framework 3.5 SP1, and my application
with the gtk dlls copied from the Mono 2.8 installation.
