multi-lingual upgrade from 4.2.9 to 4.3 fails

I replicated the above issue by running an upgrade from 4.2.9 multi-lingual to 4.3 (git repo)

Basically what happens is, during the above multi-lingual upgrade : CRM_Upgrade_Incremental_php_FourThree::upgrade_4_3_beta5 (line no:287) tries to execute a query which adds a column in VIEW (of a multi-lingual table) using ALTER TABLE clause and thus a DB ERROR is produced.

Attached is the error backtrace.
