[regression] microblogging plugin crashes

[Chris Butler]

Binary package hint: gnome-do

After "upgrading" to Lucid (from Jaunty, with a brief stop at Karmic), gnome-do is no longer able to post to twitter.

If I try to post to twitter, gnome-do crashes with the following error:

Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object
  at Microblogging.Microblog.UpdateStatus (System.Object status) [0x00000]

Also, while typing the message, I noticed the same error repeated over and over:

Microblogging.PostAction "Post to twitter" encountered an error in DynamicModifierItemsForItem: System.NullReferenceException: Object reference not set to an instance of an object
  at Microblogging.Microblog.get_Friends () [0x00000]
  at Microblogging.PostAction.DynamicModifierItemsForItem (Do.Universe.Item item) [0x00000]
  at Do.Universe.Safe.SafeAct.DynamicModifierItemsForItem (Do.Universe.Item item) [0x00000] .

When starting up gnome-do, I notice another error message:

[Error 16:45:06.953] Missing login credentials. Please set login information in plugin configuration.

At a guess, this could come from the Microblogging plugin (although it would be nice if this was included in the error!). So I tried to set the credentials in the plugin config, but that fails to validate my login details (which, trust me, are correct). Bear in mind that this was working before the upgrade, so there should be no need to reconfigure it, surely?
