Print Composer doesn't work when spanning the map object from the right side

[bjpfei]

1.) Open the print composer
2.) Click Add a new map
3.) Span the map from the upper right corner or from the lower right corner in direction left

Problem: You don't see the map object and if you make a double click in the area where you added the map QGIS crashes with the following message:

Warning: QGraphicsScene::removeItem: item 0x8727bf0's scene (0x18) is different from this scene (0x8492918)
