Comment 1 for bug 1732236

Are these you libraries or the kicad libraries? If they are your libraries you are going to have manually fix them yourself. Library IDs cannot contain ':' or '/' characters or any other character that is not allow by the file system. If they are kicad libraries, I will have to file a bug report against the library repo. This restriction will become apparent in the new symbol library file format and will have the same limitation as the footprint library names. I could silently replace the illegal characters with underscores but then someone would file a bug report that the name of the symbol was changed unexpectedly. Maybe at some point in the future I will change this but not for the stable 5 release.
