hwe-support-status crashes when option is used

[ullix]

In testing my system with hwe-support-status I encountered this problem:

:~$ hwe-support-status --show-all-unsupported
Traceback (most recent call last):
  File "/usr/bin/hwe-support-status", line 235, in <module>
    print(twrap(" ".join(unsupported_hwe_packages)))
TypeError: sequence item 0: expected string, instance found

other uses are ok:

:~$ hwe-support-status --verbose
Your Hardware Enablement Stack (HWE) is supported until April 2017.

:~$ hwe-support-status --show-replacements
[no output]

I did run the apport-collect, though as far as I can see, nothing was added.
