Hmm, that might be something else, e.g. the unhandled exception that James
fixed. James and Holger, try running rivetgun through valgrind to see if any
suspicious memory errors appear. I've had trouble running rivetgun through gdb
- it complains and stops on the first dlopen call, even though that works okay
outside gdb - and I suspect the problems might be related.

Let's try to get this fixed today.

CERN AFS is always a fallback location for generator searches, so that Rivet
will work for a lot of users without having to set AGILE_GEN_PATH.

At CERN or Hungary?
