Damaged hg repo? Where did the tags go?

If I run "hg tags" on my local archive, I get the tags listed in
.hgtags plus tags for release-3-4-0, ss-3-3-92, ss-3-3-91, and
ss-3-3-90.  Looking at http://hg.savannah.gnu.org/hgweb/octave/tags
shows these additional tags as well.  I don't know why .hgtags is
incomplete.  They are not in my local copy of .hgtags either, even
though the output of "hg tags" shows them.  Did something change with
the way Mercurial stores tags now that makes the .hgtags file
obsolete?
