Aha.   I'm getting closer.

Looking in /var/crash there was an entry for perl.   (The file itself
_usr_bin_perl.0.crash doesn't mean anything to me...)

So,  I tried just 'perl -V'  and guess what - it segfaults!

That's probably why I"ve seen other seemingly unrelated programs
segfault - lots of stuff uses perl.

So - any suggestions how to fix perl?  dpkg uses it!
