I think one of the Ardour devs has been using Git for Ardour... which is
possible to do even if the central server is Subversion.
(see http://ardour.org/node/2098) This works very effectively. I do a
lot of development this way for Hydrogen, and the only time I need to use
SVN is when I want to make an official branch or tag.

Git by itself is rock solid. I have never heard of any such issue. I
recommend it very highly.
What you have heard is possibly referring to the Git-SVN link. This link
is actually pretty stable... but it has a few gotchas.
The biggest gotcha is: SVN is able to store an empty directory in the
repos, Git is not. If you check out a SVN revision, it will create any
empty directories that were in the SVN repos. With Git, these empty
directories will not be created because there is no way to represent them
in Git. (For pure git repositories, the convention is to put a
'.gitignore' file in the directory so that it will hold its place).
As for Git vs SVN... there's plenty of chatter all over the internet about
this right now... so I won't repeat any of it. Here's some recommended
