Composer compatibility issues between 2.4 and 2.6

Original Redmine Issue: 11927
Affected QGIS version: 2.6.0
Redmine category:map_composer/printing

I have a project created in 2.4 and when I open the Composer the frame is not displayed. Moreover, the coordinates around the frame also do not appear and whatever I tried to do did not help.

There is either a incompatibility between 2.4 and 2.6 at composer level or there is a bug. I create my versions from GIT and just switching the checkout version produces this error. According to some reports that can be read at the link below the issue appears for some and not for others. This will rather point to a incompatibility, maybe deleting/renaming the ".qgis2" director could help, but I would lose all my history and settings. I will have to check that, but at the time I am under time pressure to fix some maps and for the time being I reverted to 2.4.

There is definitely a problem but we need to find what that is.
There are other issues with the composer most likely due to the same incompatibility. For example :
1) the map is set by default to Rectangle
2) after changing it to Render the map takes minutes to appear
