Where are people getting this mythical applications from is my question.
Oh right, the ubuntu repository. the same one that sanely ships things
build against same versions.

Source compiles will fail, which would happen regardless.

I don't think anything will silently break.

Ok, sorry, so #2 and #3 add permanent issues, and #1 is just plain wank,
as anything that attempts to use the assembly version (like, say, a
MonoDevelop project) will break all the time.

Which isn't even possible due to bugs in gtk# and mono (last time I

So yeah, it won't be supported.

I think it is silly for Ubuntu to ship gtk# 2.0 at all if these concerns
are an issue. MonoDevelop 0.7 should not be shipped under any
circumstances in this fashion. Muine may make more sense with private

But seriously, having all this back and forth over two apps is just not
worth it.

This is an Ubuntu concern more than anything else, and tseng should
resolve it however he wants, instead of enforcing upstream problems.
