Error from web:

An error has occurred

A problem was encountered processing your request. The tracker 
maintainers have been notified of the problem.

Installed roundup via pip in virtualenv on Ubuntu 12.04 LTS

Run command:

roundup-server -n 0.0.0.0 -l /tmp/roundup.log -d /tmp/roundup.run -u 
nobody -g nogroup rokpa=$PWD/rokpa

In the log file there are no error messages, just accesses

The error message is a bit terse. How can I find out what's the problem?

If you want an error message in the web interface you can set
debug = yes
in section [web] of your config.ini. This is turned off by default as it
might reveal information in the traceback that a user should not see.

If debug is turned off, the traceback is sent to the admin_email
configured in config.ini. If admin_email doesn't have a domain, the
config-item 'domain' in section [mail] is used. So this tries to send
mail to roundup-admin@rokpa.ch according to the config.ini you attached.

Generally: Please direct questions concerning roundup to the
