Just to be sure, are you running the Ubuntu-provided package, or
something from another package repository? Which version of Ubuntu?
Running valgrind might produce similarly opaque results without debug
symbols (which you can enable if you build from source).
debug syms are available as separate debs.
As an example, for Ubuntu, look here:
https://wiki.kubuntu.org/DebuggingProgramCrash
then look for installing {nut,libupsclient}-dbgsym and others if
needed otherwise...
That is a bit
more involved, though (especially if you want to keep the installed
files in the same place) so I'd try that after Arjen's suggestion with
"-DDD".
seconded for a first run.
cheers,
Arnaud

The only extra package I could find is the "dev" package. I'm not sure
if that contains debugging symbols.
I'm running with the "-DDD" option now. It hasn't crashed over the
weekend, so we'll see how long it takes to crash now. I'm getting
source to try and rebuild it so that I can walk through in GDB if necessary.
Thanks.
