When executing "Rebase" action from Promoted Builds, it skips with indication that it's not an SVN project

Building on master in workspace D:\jobs\feature-trunk-slav-personal\workspace
Promoting feature-trunk-slav-personal #68
Project does not build a Subversion feature branch. Skip rebase action.

I understand that Promoted Builds don't appear like normal builds, however the "Rebase from Upstream" manual action always works on latest WORKSPACE anyways, so being able to trigger it from promotions (for reasons for checking tests/QA approval first) would be much appreciated.
