Segfault when using ralabel Version 3.0.6.2

[Carter Bullard]

Hey Jesse,
So what is in that flow_label file ?
So we're blowing up reading the file.  I suspect that we're either running out of
array space somewhere, or there is a syntax error that we're not handling well.

Can you share your flow_label file ?
