"Everybody stand back, I know regular expressions..." 
In the split_tags method instead of tags.split... do:
tags.scan( /(.*?=[^=]*)(?:;|$)/ ) do |tag| ...
This will effectively split tags based on the combined presence of = and ;
rather than just one or the other.
It fixes the whole PGS blah thing.
It's still fairly trivial to come up with strings that break it, but they
mostly rely on using equals.
; and = should really be escaped. But that requires a much bigger fix.
