[Evolution-hackers] [PATCH] Fix a possible segfault

[Christoph Höger <choeger cs tu-berlin de>]

I am not 100% sure on this one, but abrt reported a crash in line 203.
The value of mi was optimized out and there was no debugging info from
the causing function (in general abrt seems to be far away from really
 usefull), but since mi _can_ be NULL here and the get_flags operation
derefernces this pointer without further checking, I guess this is the
correct solution.
