Digikam's gpssearch tool uses marble widget to help people search their photos geographical. To search photos on the map, one has to draw a rectangle over the map and the photos inside it will appear on the icon-view.
The problem appears here when one tries to draw a rectangle across date boundaries. When that happens, the rectangle transforms into a polygon having different forms. Here is the code that I use to draw the rectangle: http://pastebin.com/2rkzkxp6 . I've also attached a screenshot to make a better idea of what the problem is. If you want to experiment the problem, you should compile digiKam's branch (http://websvn.kde.org/branches/extragear/graphics/digikam/), because this code hasn't been released yet.   

Reproducible: Didn't try

Steps to Reproduce:
Draw a rectangle from Japan to Mexico above Pacific Ocean.

Actual Results:  
The rectangle changes it's shape.

Expected Results:  
The rectangle should remain a rectangle.
