win32: FileChooserWidget + gtk_window_set_deletable

[Felix Kater <fkater googlemail com>]

Hi,

could anyone please say if this should be considered a bug -- if so,
I'd file an issue at bugzilla:

* use win32 (not yet tested on linux)
* create toplevel window
* gtk_window_set_deletable(window,FALSE) [this is the critical part]
* place a FileChooserWidget into window
* show window
* click button to display the address entry line (whatever called)

result:
* the window is shrinked to the title bar only
* when double-clicking title bar -> window gets full size

note:
* when gtk_window_set_deletable is not used -> works as expected



This is just a demo, if anyone is interested I could also create some
real code.

Thank You
Felix
