But Eli's got a good point: the one with a NULL dirname is at best
sub-optimal.

There are two potential sources of duplication: bugs, e.g. in our
processing of symbol vs. line information, and actual duplicate entries
in the debug info.  As Susan correctly noted, the duplicates are often
legitimate and discarding them entirely would be bad.  But it sounds
like the ones you're observing are the result of a bug.
