bug#6139: 24.0.50; tool-bar-style

[Stephen Berman <stephen.berman@gmx.net>]

My latest update includes the new feature of configuring the tool bar to
display text via the tool-bar-style variable, with the default value
nil, meaning system default.  My desktop is KDE with the gtk-qt engine
for GTK+ applications.  When I start Emacs with -Q, the tool bar over
the *scratch* buffer has text below the icons, but as soon as I do any
input event (cursor movement, mouse click, etc.), the text disappears.
When I start Emacs with -q, when the tool bar appears in the frame there
is text below the icons, but the text vanishes within a fraction of a
second (before any input event from me).

In GNU Emacs 24.0.50.1 (i686-pc-linux-gnu, GTK+ Version 2.18.6)
 of 2010-05-07 on escher
