I agree.  How about letting plugins raise an exception  
("PluginFailedException"?) which causes bzr to silently ignore the  
plugin.  That way, the SFTP plugin could immediately abort when  
paramiko fails to load (possibly logging a warning?), but not hook  
itself into bzr and not cause bzr to abort.
