You're right, even the newest versions cannot achieve the upgrade. The
problem arises with local Default.commands files created with (some?)
old versions. The workaround is to delete
~/.denemo-xxx/actions/Default.commands before doing the upgrade and then
re-instating custom commands via the More Commands menu item.
(Which is what you did. The alternative is to add the leading slash to
all the path names in <menupath>....</menupath> where they are missing
in Default.commands. It is the lack of the leading / that is causing the
crash.)

Thanks for helping nail this.
