What steps will reproduce the problem? 1. compile dcsharp on gutsy...then run it if you are behind a proxy...you might see this...

An unhandled exception occured:

System.Exception: org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Notifications was not provided by any .service files

compiled with gmcs...run on mono(if that's of any importance)

Thanks for the report. You need to install the notification-daemon package or use the latest version from the repository. (This is a duplicate of issue 3)
