Dear all, manually placing labels when using clabel seems to be broken in Matplotlib 1.3.0.
I'm on OS X 10.8.5 and have Matplotlib installed via macports. Today I updated all installed ports and thereby got the new version of Matplotlib. Now manually placing cline labels creates weird artefacts. I attached a demo script at the bottom and uploaded a screenshot at http://i.imgur.com/u6BLcRB.png . As you can see there is also a depreciation warning. Now I downgraded to Matoplotlib 1.2.1 again (keeping all other updates in place) and the problem is gone. I currently have very little time for bug hunting and therefore will just stay away from updates for a while. Maybe someone can figure out what's going wrong.
