I bumped into a problem with witter. I'd forgotten to configure OAuth and witter just hung on startup when trying to retrieve my timeline. I've posted a bug report about this. If anyone else bumps into this problem I solved the issue with witter hanging on start up by opening xterm and typing: Code: mv .witter .witter.back You then have to setup your twitter account details again making sure that you configure OAuth in the account setup screen.
mv .witter .witter.back
