I am confirming that gimp 2.6.10-1ubuntu3.1 from maverick-proposed resolves the issue.
It does not pull dependent packages libgimp2.0 and gimp-data to the corresponding new version (2.6.10-1ubuntu3.1) though, but it's merely cosmetic issue and doesn't matter in this case.
Many thanks to all who chimed in and made it work.
