[Message part 3 (text/plain, inline)]

In GNU Emacs 23.0.60.24 (i686-pc-linux-gnu, GTK+ Version 2.12.9)
 of 2008-12-15 on escher
Windowing system distributor `The X.Org Foundation', version 11.0.10400090

When I detach the tool bar, what looks like a one pixel gap appears in
the bottom border of the menu bar below the `F' in `File'; here is an
image (made from emacs -Q):

[Message part 5 (text/plain, inline)]

I do not see this when I disable tool-bar-mode; however, in that case
the menu bar has a different appearance than with a detached tool bar:

[no-missing-pixel.png (image/png, attachment)]

[Message part 7 (text/plain, inline)]

I just noticed the missing pixel now, after updating from the trunk, but
I cannot say for sure when it first appeared.  I checked all the GTK+
Emacs binaries I have, going back to 22.1.50, and they all display this
gap, and I'm certain I didn't overlook it all that time.  This suggests
it's a recent bug in GTK+ or a library used by GTK+.  My (openSUSE 11.0)
system updater installed patches to glib2, libglib, libgmodule,
libgthread, libgobject, libgio on 2008-12-10, so this seems a likely
source. I'm reporting it here because I have no other GTK+ app with a
detachable tool bar, so I want to make sure it's not an Emacs bug.  If
Jan or another GTK+ hacker can confirm it's a GTK-related bug, I can
submit this report to the appropriate list or bugtracker.

I don't think that is a missing pixel. It is the snap-back space for the tool 
bar, so you can snap it back into place.  The Gtk documents says:

"A thin ghost is drawn in the original location of the handlebox. By dragging 
the separate window back to its original location, it can be reattached. "

The size of the ghost is 3 pixels for my version of Gtk+.  I'm closing this bug.
