To get a backtrace I suggest using gdb as described in this forum
thread: http://forum.freeciv.org/viewtopic.php?t=1887
For further debugging I'm using Eclipse with the CDT plugin, which has a
very nice gdb interface.
Backtrace and fix for this crash are attached. The client (gui part)
asked about details of unknown tech.
