I did bisect again and I did get a different result:

c1518f12bab97a6d409a25aaccb02dc8895800f3 is the first bad commit

Trying to revert that commit gives:

$ git bisect reset
$ git revert c1518f12bab97a6d409a25aaccb02dc8895800f3
fatal: Commit c1518f12bab97a6d409a25aaccb02dc8895800f3 is a merge but no 
-m option was given.

How am I supposed to proceed now ? (sorry I'm a git newbie)
