Very much tnx to gd_on!! I removed all \r, so that only \n are remaining in the po-file and o wonder, the translation appears completey in the IDE.
The po-file (codeblocks-gms-de_1-000-178a.po) i've uploaded to launchpad for free use. I think, only 2700 from more than 8000 lines are translated. If you want, I can send you the file via Email, cause upload here isn't possible. My Email-adresse is info@rechtsanwaltsteyer.de
