-------------------------------------------+---------------------------
 I was experimenting with the SFTP server and I accidentally pasted a
 malformed (truncated) cap into the config. It reports this reasonably well
 when I try to use it:

 {{{
 lftp acct at 127.0.0.1:~> ls
 ls: Access failed: cannot list an unknown cap as a directory. Upgrading
 the gateway to a later Tahoe-LAFS version may help
 }}}

 (Actually that's not a great error message — it should tell me that this
 is a malformed cap, not a cap of an unknown type — but that's the topic of
 a different ticket.)

 It would be better if it reported this error as soon as I login rather
 than waiting until I try to "ls" something.
