Hopefully someone else with deeper tag knowledge will answer this, but
I'm pretty sure Mercurial scans the contents of .hgtags on all the
branches/heads, so the bad tags would need to be removed on all of them.

While hgk is invoked by the TortoiseHg context menu, it's not
technically part of TortoiseHg.  Since you're using the all-in-one
TortoiseHg installer, it also comes with hgview which you can use in
place of hgk.  Since hgview doesn't spawn hg subprocesses, perhaps it
will be more robust against the tags problem.  Just change your
Mercurial.ini file to read:

[tortoisehg]
view = hgview
