[SR-Users] Segmentation fault when loading dialplan

[Daniel-Constantin Mierla]

Thanks, I will look over it and try to reproduce in the lab, it may take 
a bit since I am pretty much time offline these days.

Can you add a second rule and see what happens? At the first sight of 
the debug messages, the result from database is ok, should not be a null 
value there.

Cheers,
Daniel
