Comment (by akaariai):
Yes, that one fixes the issue. Instead of getting apps not ready
exception, I can see the original exception on command line. If I fix the
error in the settings, the project is correctly reloaded.
If I start the runserver with an exception caused by a mistake in
models.py of some installed app, then I get the following exception:
{{{

I guess we want to avoid that.
