problem with file chooser using gtk+-2.18.9, OK with gtk+-2.16.6

[Sergei Steshenko <sergstesh yahoo com>]

Hello,

I've upgraded from gtk+-2.16.6 to gtk+-2.18.9 and noticed a problem with
file chooser - Perl bindings are Gtk2-1.221 in both cases; the rest of the
libraries is the same for both cases.

The problem is that clicking on OK button or just hitting <ENTER> doesn't
work. The positive feature of gtk+-2.18.9 file chooser is that remembers
last visited directory, but this defect makes it almost unusable. The only
way to enter a directory is to double-click it.

Is it a known problem ?

Thanks,
  Sergei.
