Procedure:
1. Edit > Preferences > Name Resolution > Edit SMI modules
2. Add proprietary MIB that includes the following section
   label MODULE-IDENTITY
       ...
   ::= { parent 1 }
   where parent was not defined by mistake.
3. Close all dialogs and exit Wireshark
4. Wireshark will crash during startup from then on

Workaround:
1. Delete the offending MIB file before starting Wireshark. An error message
will be displayed during startup but at least we avoid crashing.
2. Fix the offending MIB file.
