Sorry i forgot to mention. It is the GOG Version 1.12.1_03142_48164 Linux, including the Making History and Breaking Ground DLC
I deleted everything and reinstalled it from scratch , used CKAN to install MechJeb2, Kerbal Engineer Redux and ModulManager 4.1.4
Nothing else, and the file is there.
It contains 11521 lines of German text in the Format like the example of line 10 down below: (every line starts with 2 Tab keychars)
#autoLOC_6005084 = Europäische Weltraumorganisation
Unfortunately the log does not say in which line exactly the parsing error appeared, there is for sure not a single line beginning with ":" but the very last line is empty.
PS.: I took a look at "dictionary.cfg" at the same location, at least the line from above is in there and it is a little bit better formatted (within curly braces and things), while "temp.cfg" contains just only "#autoLOC..." lines, maybe "temp,cfg" is really only there by a packaging mistake and not needed.
Thanks
