Hi all,
I just commited this fix to the 1.1. branch because TurboGears will hang
(and could only be killed with a KILL signal), when an exception occurs
in 'startup.startTurboGears'. This could happen when you tried to open
the toolbox in a project with identity, but no ORM is installed.
But I'm not totally happy with the fix, because it essentially silently
ignores errors when loading TurboGears extensions (though it logs them).
If you look at my other commits before this one, you can see that I
tried prevent users from starting a project which needs a ORM when none
is installed, but still...
Anybody has any better ideas or comments?
