Use plain git.
Suppose you're on branch called foo

git fetch trac u/gh-timokau/rpy2-build-typo
git checkout -b rpy2-build-typo FETCH_HEAD

at this point you have created a local branch called rpy2-build-typo
which is more or less what trac extension is supposed to do.
Test is, and then do

git checkout foo

to get back

Why?

git repo itself does not know anything about trac tickets. It's git
trac extension that tries to match tickets to branches somehow.
