QGIS » QGIS Application

1.) Open a QGIS-Project A (in my case some Shape and DB-Layers) where the map composer contains at least one map window

2.) Change to QGIS-Project B with Open Recent Projects. This project should also contain at least one map window in the map composer

3.) Open the map composer

4.) Close the map composer

5.) Change the QGIS-Project and open Project A

6.) Open the map composer

7.) Close the map composer

8.) Save Project A

9.) If you now check the .qgs-File with a text editor you can already see more than one composerMap. In QGIS you still see one map window

10.) So close QGIS

11.) Open QGIS and load Project A. In the map composer you can see three map windows now.

I know this isn't a very reasonable example. But if you are working with different projects you can easily run in these problems.

Happens with code revision 10876
