I can't reproduce this on my machine.

In order to do anything about this issue, I need one of the following:

Option A: A series of steps which somewhat reliably trigger the problem.

Option B: A core dump from the crash and associated binary files.  In 
order to achieve this, compile gEDA/gaf with CFLAGS="-g -O2" or (even 
better, but may hide the bug) CFLAGS="-g -O0" and enable core dumps, e.g. 
by invoking gschem as

     ulimit -c unlimited && gschem

Then, pack the resulting core file and the /bin and /lib directories from 
the gEDA/gaf installation into a tarball and upload or send it to me. 
Note that, since the core file contains a memory dump, it may contain 
private information (e.g. the schematic you were working on).
