zotonic upgrade to 0.6 from 0.5 not working due to menu problems

[GoogleCodeExporter]

When I try to load my site I built on 0.5 on Zotonic on the default
branch I get HTTP 500 error.

I also get what appear to be multiple retries of mod_menu to upgrade
my menu to the new model.  It seems to be failing because it can't
find the RscId for my menu at 
http://code.google.com/p/zotonic/source/browse/modules/mod_menu/mod_menu.erl#48.
Do I need to start the site on 0.6 first and then restart on default?

Here is a transcript:

I think the problem is this:

you have a resource in 0.5 which has the name  "menu". 
Therefore, the menu module cannot make the *category* "menu", and cannot insert 
the default menu rsc (named main_menu).

Next, when upgrading the old menu structure, this fails because the "main_menu" 
rsc cannot be found.

Try deleting/renaming your rsc which is named "menu", and see if that helps.

considering resolved.
I just upgraded a production site 0.5 -> 0.6 without this issue.
