Public bug reported:

Hi,

plasmashell crashed on my system, and when apport tried to upload the
problem report, 2 Python errors occurred:

TypeError: cannot use a string pattern on a bytes-like object
TypeError: startswith first arg must be bytes or a tuple of bytes, not str

Here is more context:
