This is because the GECOS field contains a string starting with a '+'
(for example a phone number) and the string that is replaced in the
regex to anonymize user name is not escaped.
The code below is an excerpt of apport.report.anonymize(self) that reproduces
the issue:
==========
import re
p='My User-Name,12.123,+123456789,+123456789,'
replacements=[]
for s in p.split(','):
s = s.strip()
if len(s) > 2:
print(s)
replacements.append((re.compile('\\b%s\\b' % s), 'User Name'))
==========
The GECOS field should be escaped as it contains general information and
forbidden characters in regexp.

field in apport.report.anonymize()
** Description changed:
I'm getting this bug, actually in just one system and one user, I don't
get it for instance in the "guest" account. I don't get it either if i
run the apport comment with "sudo".
In the terminal I get:
