I reported a similar problem with the xview packages yesterday. I've
been strace-ing dpkg, and what happens is this:
symlink("/etc/blabla", "/usr/doc/xview/blabla.dpkg-new");
chown("/usr/doc/xview/blabla.dpkg-new", 0, 0);
This fails if /etc/blabla doesn't exist already. This only happens with
some packages, because in others the file being linked to is in the
data.tar.gz file earlier on, so it exists. A quick workaround is
"touch /etc/blabla" before running dpkg, I've discovered. Not good,
however.
The SIGSEGV is in "paste", I think. Also not good. I'll investigate that
further (a utility should never crash, irrespective of unexpected input).
This was with 2.1.87. With 2.0.31 it works fine.

Hmm, maybe not yet in 2.1.87? I'll try the latest next week.
