 Sometimes the Palette for Journal list view entries doesn't appear and the
 details view is broken. There's a series of Tracebacks like the following
 in shell.log:

 {{{

 I have no idea how to trigger this reliably. So far, it happened only
 while being connected to a Jabber server. Switching to Salut (even though
 that's broken inside chroots) "fixed" it, as did restarting Sugar (with
 the server setting back to jabber.sugarlabs.org).

 Filing against sugar because {{{filetransfer.file_transfer_available()}}}
 should just return False if something  is broken (and probably log the
 exception).
