[Bug 2146806] Re: Python TypeErrors

[Benjamin Drung]

Can you attach /var/crash/_usr_bin_plasmashell.1000.crash? ProcMaps
should be a string, but somehow is not for you. I like to see what is
inside on your report.

** Summary changed:

- Python TypeErrors
+ TypeError: self["ProcMaps"].startswith first arg must be bytes or a tuple of bytes, not str
