When I disable the tool bar before entering the Gnus Summary buffer and
then re-enable it while in that buffer, it appears as an 8-pixel high
empty strip below the menu bar.  When I switch to another buffer, the
tool bar is displayed normally but the frame height increases by two
lines, and when I switch back to the Gnus Summary buffer the tool bar
again appears as an empty strip and the frame height stays at the new
height; this pattern can be repeated and each time the frame height
increases.  I see the same thing when the tool bar is displayed at the
bottom of the frame; if it is displayed on the left or right side of the
frame, the frame width increases instead of the height.

I see this in builds from emacs-25 and master, as well as in 24.5, all
64-bit GNU/Linux, GTK+ Version 3.14.15 (not built --with-cairo).  In the
24.5 build, when switching back to the Gnus Summary buffer, the console
displays a message like this:

(emacs:4487): Gtk-WARNING **: GtkToolbar 0x313ca90 reported min size 42
and natural size 8 in get_preferred_width(); natural size must be >= min
size

There is no such message with the emacs-25 or master builds.  (In the
latter two builds, the initial frame height is 36 and increases to 38;
in the 24.5 build, the initial height is 35 and increases to 37.)

I haven't seen this issue with any other buffer than the Gnus Summary
buffer.  Moreover, if I disable the tool bar only after entering the
Gnus Summary buffer and then re-enable it there, the tool bar is
displayed in that buffer normally and there is no resizing after
switching away and back.

To reproduce, start emacs with -Q and evaluate the following sexp in
*scratch*:
