Even the original changeset that introduced the use of the file chooser
(a20218704019) crashes in cygwin. I've been able to get other
applications (eog) to build and run in cygwin and use the file chooser
there. So, it doesn't look like this is a problem specific to the
cygwin port of the Gtk libraries.
If need be, cygwin builds could use the old file chooser but that
doesn't help with the goal of removing old Gtk code. Remember, the old
file chooser is likely being removed for Gtk3 along with all the other
In the 2+ years the file chooser was active, before being disabled in
7.2b.026, there weren't any reported bugs that I can recall about gvim
crashing when using the file chooser. I'm only subscribed to vim-dev,
though. At any rate, it seems that either the bug didn't exist back
then and Gtk/Glib has changed in such a way that Vim's use of it is now
wrong or no one encountered (due to not using the file chooser) or was
bothered enough to report the bug.
