Good that you got around the problem. However not good that Ethereal crashes when net-snmp
has problems parsing some mib-files or similar. 
But I'm anyway happy that net-snmp support is included in the Windows binary now from
Ethereal version 0.9.8. I have been using Ethereal 0.9.1 sometimes for looking at SNMP captures.

The file I had problem was the Diffserv-PIB (PIB converted to MIB) from the following message, and
another mib-file that seems to be corrupt. 
http://www.ethereal.com/lists/ethereal-dev/200202/msg00272.html

I had the same mib-files in /usr/mibs/ when using Ethereal 0.9.1 (with ucd-snmp)
and then I didn't notice any problems.

With Ethereal 0.9.8 I got a crash on Windows 98:
ETHEREAL orsakade ett ogiltigt sidfel i   (page fault in module ETHEREAL.EXE on address 015f:0067314c)

Seems to be same address in your case (0067314c).

On Windows 2000 nothing seems to happen when I double clicked on the Ethereal icon. 
No GUI appears. I notice in Task Manager that ethereal.exe process is there. It seems Ethereal is hanging during startup.

I will try to look into this later this week and if it seems to be a problem with net-snmp I will
report it to http://sourceforge.net/projects/net-snmp/. I noticed that there seemed to be a couple of messages
about looping for ever for certain MIBs or similar, so it may be a problem that already has been reported.
