apport ends with Segmentation fault

[Muriel]

There are three problems with apport on kubuntu 16.04:

1) Missing dependecies: python-pyqt5

2) Exception running the application:
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 21: ordinal not in range(128)

3) Segfault at the end of the program, even if the information is sent correctly to launchpad.

Regarding 2) can be fixed with:
