Control: severity -1 important
I fetched the sip source and tried to figure out what is going wrong,
and was able to get this gdb backtrace and source location:

Using this I managed to figure out that a way to avoid the segfault is
to specify '-n something' on the command line. May I suggest sip is
extended to report a sensible error message instead of segfaulting, if
'sipName' is not set?
I'm lowering the severity to important, as there is a well known and
easy to apply fix.
