Then the middle would be 28 Jan.) 2) Update your sources to the middle. 3) Check whether problem is present? Goto 1). You loop in this cycle until you come to a small timeframe with a few commits. Then you either determine which one is problematic logically, or try to apply them one by one. Once you habe found the problematic commit, you contact its author. -- Totus tuus, Glebius.
