With a quick glance at the KTooN codebase, I made the following observation:

The KTooN commits from 2010-05-15 11:48 and 11:49 with message "Updating license version from source code -> GPL 3" changed the license from "GPL v2 or any later version" to "GPL v3 or any later version".

(Please correct me if I am wrong, the commits change about 1000 lines and I did not check every change!)

From my POV you have two options. Both include first asking _every_ commiter following up the license change commits in a documented way if they allow changing the license to "GPL v2 or any later version". After you received their approvals you can:

Either

* revert the two license change commits

* do a rebase of all following commits

* change newly introduced licenses

Or

* revert the license change commits and perform relicensing at once.

I see no need to contact Monica about that issue, since all approvals that are necessary for doing the relicensing are from individual commiters (who commited after the relicense in 2010, as far as I understood).
