Status changed to 'Confirmed' because the bug affects multiple users.

This also affects me on 11.10 server.

Me too, 11.10 server (uwsgi 0.9.8.1).

When I try to restart uwsgi it fails and in the log file I get (not so helpful until you read the source code)

    opendir(): No such file or directory [uwsgi.c line 297]

Solved with wdoekes solution

    mkdir -p /usr/lib/uwsgi/plugins

I hope this helps others as google wasn't much help to me.

Can confirm. Creating the missing folder solves it for me, too.
