["Zhan Shi" <zhan_shi@xxxxxxxxx>]

<URL: http://rt.freeciv.org/Ticket/Display.html?id=11259 >

Whenever i double-click a city or select the "popup"
city button in the message box, my client crashes with
a "segmentation fault"

I used gdb to produce this bug trace;

I am using version 1.14.2 and compiling it on MacOS X
(10.3.4).

This problem isn't urgent or anything, just thought it
might be beneficial to let you know about it.

Great work with the software!
