I don't know how fragile it is as I haven't worked according to this
workflow. I only copied what I have learned from reading various
resources. However, I call it fragile, because to use git svn safely in
workflow that synchronises projects in both ways, in-depth understanding
of SVN and Git is necessary, IMHO. Especially understanding of Git
because Git is such a powerful tool that it is possible to do things in
many ways.
Otherwise, it is easy to break things.

Here are the two resources I can recommend:

http://learn.github.com/p/git-svn.html

http://progit.org/book/ch8-1.html

If you look at the last sections of both, it is "Rules and Guidelines"
and "Git-Svn Summary", you will notice quite a number of "health and
safety" rules included in those fairly short paragraphs.
This tells me, it is easy to blow things up.
