I noticed by doing some builds on my own, that COdeBlocks states to be revision 3860 - wxGtk2.6 I tried to get rid of this by uninstalling CodeBlocks vie apt-get remove and reinstall a fresh build, but it did not help.
What I can say for sure ist, that it actually is build against wxGTK2.8 because there is no "Drag'n'Drop - Bug". I also completely removed every folder of c::b in /usr/ I could find without success.
This is a minor Problem as CodeBlocks works fine and with al the pros the new version offers but I would be glad having an true Number in the info.
