Log:
 Prevent potential crash in libsmi.
 From: Vincent Bernat <[email protected]>
Since SVN #32006 was committed, the following messages appear when tshark and Wireshark are started.
For Wireshark the messages appear as popup Windows which must be 
dismissed !!
----------

tshark: Stopped processing module SNMP-COMMUNITY-MIB due to error(s) to prevent potential crash in libsmi.
Module's conformance level: 0.
See details at: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=560325

tshark: Stopped processing module SNMP-MPD-MIB due to error(s) to prevent potential crash in libsmi.
Module's conformance level: 0.

Needing to dismiss popup windows each time Wireshark is started is obviously a non-starter. :)
So; What should be done ??  (I know zilch about SNMP MIBS).

I wanted to commit the attached patch, but I realized, that preferences are read _after_ loading the SMI modules. :-(
Could we read prefs earlier, maybe twice?

I also asked Vincent about a potentially better workaround [1].
We can remove the buggy(?) MIBs from the default list of MIBs to be loaded, but it would not help users with older preferences file. :-(
I can turn the popup to a debug message, but silently skipping the 
modules does not seem to be a good idea.
Cheers,
Balint

I've committed a refinement to the workaround based on Vincent's email [1] in 32017.
