came about due to the fact the Python documentation did not
state that crc32/adler32() implicitely convert input, if
needed. I have fixed this problem by adding an explicit
encoding step before passing in invoice IDs.

The fix will be in 1.7.9, meanwhile you might want to try
copying the attached file into the 1.7.8 tree, but do note
that I haven't tested that to work.
