No, MySQL2 old-stable does not need to be used at all, Redmine is
compatible with Rails 3.2 [1] via the 2.x branch [which is stable as the
1.4 branch.]  Actually it would probably make management and bug
handling a bit easier, read below for more.

There really is no need.  If one keeps the old MySQL active for now
until rdepends of it die or get updated and then just upgrades Redmine
to 2.x, which supports both MySQL on 1.8 and MySQL2 on 1.9 [with no
version dependencies] then all should be well IMO, but 1.8 is as good as
dead to some, and so are some versions of Rails (even if they get
security updates for now.)

This should rid of quite a few old packages that keep hindering, but
that outlook is subjective and optimistic since I can't assume what the
maintainers will do.

What I mean by all that is... Just adding MySQL2 latest and Redmine
latest should solve the problem IMO and the rest will resolve itself as
1.8 finally dies for good and Rails 2.3 dies for good too.

I really think Redmine should be pushed to the 2.x branch which would
fix this bug, but I assume people will object to that because they might
have a lot invested in 1.4 and I don't assume there is an easy way to
manage everyones upgrades in a straight forward manner, but when we
upgraded here the path was pretty easy [2]
