org.hotot.service.update_status: tweets disappear when post unsuccessful

[teranex]

I created a plugin for Kupfer (http://engla.github.com/kupfer/ ) (plugin available here: https://github.com/teranex/kupfer-plugins/blob/master/hotot.py ) which let's one create Tweets directly from Kupfer by using the running Hotot instance. To do so I use the org.hotot.service.update_status method. This works fine, except when the tweet can't be posted (for example because it is too long), then the tweet seems to be 'lost'. Would it be possible to return a status-code through D-Bus, or, alternatively, add the tweet as a draft when posting fails?
