When you save and there is an edit conflict (even with a different section), not only does the edit conflicts screen appears (as expected), but also the edit is saved (it shouldn't). This causes a lot of confusion. http://en.wikipedia.org/wiki/Wikipedia:MW_1.5_bugs#Edit conflicts not working anymore, and section edit broken
See also bug 2573.
Solved by Brion's fix to the edit conflict detection
