Bug Description

Binary package hint: mythbuntu-control-centre

I found out that I had an empty line in my /etc/passwd file, I am not sure if that is officially possible. Anyway, then in the core.py file (see apport report) the code falls over because 'fields' doesn't contain any values:

        def populate_user_ids(self):
            """Returns all valid user id's for autostart"""
            self.user_count=0
            in_f=open("/etc/passwd")
            for line in in_f:
                fields = string.split(line,":")
[l148] id=int(fields[2])

Please find the debdiff which fixes this issue attached to bug #241402 (bug_241402_0.28-0ubuntu1~hardy2_to_0.28-0ubuntu1+hardy1-second_try.diff).

TEST CASE: Add empty line to your /etc/passwd, start MCC and watch it fall over. After applying the patch, it should start just fine. *CAUTION* messing with your /etc/passwd can result in a broken system! Do not try this unless you really know what you're doing!
