I opened a ticket at https://pharo.fogbugz.com/f/cases/11797 but I'm not sure how I am supposed to provide fixes made against a pharo2.0 image. Probably I should fix this againt 3.0 but then I'm still a 2.0 user :)
The best is to have two issues: one for 2.0 and one for 3.0. Then we can first commit it to Pharo3, test some days and then do the pharo2 version
(you need to do two slices, one for 2.0 in the 2.0 inbox and one for 3.0)
