Details:

Freeciv v2.4.1 compiled on OpenSuse 12.3 with KDE, using Gtk-2.0

I get the following errors repeatedly during game play:
(freeciv-gtk2:25370): Gdk-CRITICAL **: IA__gdk_window_process_updates:
assertion `GDK_IS_WINDOW (window)' failed

(freeciv-gtk2:25370): Gtk-CRITICAL **: IA__gtk_widget_get_state: assertion
`GTK_IS_WIDGET (widget)' failed

after a while of playing (a couple of hours), the game slows down drastically
(movement of units becomes noticeably slow, opening a city window is slow,
moving about the map window is slow, etc.), and I start getting these errors:
(freeciv-gtk2:2148): Gdk-WARNING **: XID collision, trouble ahead

If I save the game, exit out of the game, restart, and reload, the errors go
away for a short time, then return.

>From YAST on my system:
gtk2-devel package is version 2.24.18-2.4.2
compiled using gcc version 4.7-7.1.1

I can see the above errors by opening a Konsole session, cd to the freeciv
directory, and executing:
./fcgui
This is followed by the following messages:
Unable to find client executable: freeciv
Searching for freeciv clients ...
... using ./client/freeciv-gtk2
Running ./client/freeciv-gtk2

When I watch the Konsole window, that's where I see the above gtk and gdk
errors. 

I also have the bug where the combat animations do not appear, but fixed by
running this:
export OXYGEN_DISABLE_INNER_SHADOWS_HACK=1
and by adding this line to mapview.c in flush_dirty:
gdk_window_process_updates(gtk_widget_get_window(map_canvas), FALSE);
These are the only two modifications I have installed.
The combination of these two fixes corrects the problem with animations not
appearing.  

I would be happy to provide any files from my system if needed.
