Actually, the whole ValueError here is "only" about quite a recent(3.5.4+ and 3.6.3+) change in the CPython internals in this pull request which basically for our ctypes clipboard meant calling a changed API _PyUnicode_AsUnicode instead of the original PyUnicode_AsUnicode and as described in the commit message:

_PyUnicode_AsUnicode() which is similar to PyUnicode_AsUnicode(), but checks for null characters..

it raised an error. It took a while to figure this one out because I didn't find it in the release notes, however it's fixed in kivy#5579 and will be soon in master branch.
