Mine was apparently a problem with the installation of the toilet bowl as well. We got a new plumber to reinstall 1 month ago but the problem is back again..

I have the same smell in my toilet as well. The HDB guys are unable to trace the source of the problem (after coming down more than 4 times). They suspect that it might be a small crack in the air vent.. Harry, you managed to solve the problem?
