You might re-try the conversion using the [hgsubversion extension][1]. It's designed to allow two-way use of a Subversion repository from Mercurial, but as a consequence it can sometimes handle a simple one-way conversion better (and faster).

Neither `hg convert` nor hgsubversion will likely be able to handle subdir tags automatically, though. You might have to manually add the tags after the conversion. If you're using a current version of hg (>= 1.6), this can be done relatively easily:

    $ svn log svn://example.com/original/repo/tags/subdirtag  # note revision number
    $ hg tag -r 'svnrev(X)' TAGNAME                           # X is revision number
