Confirmed. I've just reproduced this. I'll add in some bullet
proofing to the get_proc() routine to try to prevent this from 
happening..

Created attachment 83489 [details] [review]
Patch to hopefully fix the problem.

The get_proc() routine will now check for an empty buffer and if found,
just return.

Committed to SVN trunk/HEAD (revision 1535). It'll hopefully
make it into the next gcalctool tarball in time for GNOME 
2.18.0 (final).
