[Freeciv-Dev] CVS seg faults (GTK client)

[Greg Wooledge <wooledge@xxxxxxxxxxx>]

This is my first time playing the GTK Freeciv client (I've always played
the Xaw one before now).  The seg fault occurred when I clicked on my city
(Babylon).

Program received signal SIGSEGV, Segmentation fault.

Compiled with egcs 2.91.66 under Debian GNU/Linux unstable (x86) with
libgtk 1.2.1.

The following warning appears (twice) in the window from which the client
was run:

GLib-CRITICAL **: file gmem.c: line 723 (g_mem_chunk_free): assertion 
`mem_chunk != NULL' failed.

Here's a little more information -- but I don't understand the GTK
client at all yet, so I'm not sure what to look for.
