Config WireShark to load the same MIBs.

In 0.99.6, it works well.
In 1.0.0, it crashed on startup.

I am sure it's caused by loading MIBs.
If I remove SMI settings, it starts normally.

I have to point out, my MIBs can only pass paring level 'Lenient' on my MIB
browser (AdventNet's MIB Browser).
I tried to modified MIBs to pass level 'Normal'.
Sometimes it solves the problem. But most of the time, it doesn't.
So I don't think MIBs are not the problem.

I also tried to change the loading order of SMI modules.
Sometimes it solves the problem, though I don't think it's the right solution.

I think the root cause of this problem is, what's the difference of MIB parse
between 0.99.6 and 1.0.0 ?

I am not providing my MIBs at this time, because it's owned by my company
In case you need MIBs to test this bug, please inform me and I'll try to give a
copy (with some modification).
