Hi,
when trying to debug cython3 modules from gdb build also with python3,
you get a error in gdb plugin code "Python Exception <class 'TypeError'>
must be str, not bytes:". This is because in Cython.Debugger.libcython
during "cy import" or "cy break" a bytes object is passed to
gdb.string_to_argv, but it expects a normal str. I attached a simple fix
that worked for me, but I don't know enough about the gdb's plugin
system whether it will hold in all cases.
The gdb version I ran into this with is 7.10.1.

Subject: [PATCH] don't convert string_to_argv argument to bytes
neither shlex nor gdb expect this
