empty merge to default, resulted in cache corruption:
$ hg up default
1 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ hg merge stable
2 files updated, 0 files merged, 0 files removed, 0 files unresolved
(branch merge, don't forget to commit)
$ hg ci -m merge
$ hg log -GT'{rev} {tags}\n'

remove corrupted tags cache and run log, the tag resurrected:
$ rm -R .hg/cache
$ hg log -GT'{rev} {tags}\n'

recreate cache explicitly, which makes the cache corrupted again:
$ rm -R .hg/cache
$ hg debugupdatecaches
$ hg log -GT'{rev} {tags}\n'
