Unfortunately, I poked around the changelog for the NcFTP client,
and saw nothing relating to this bug.

Hehe... I often find humans with similar problems are quicker than
Google. :)

I did just spend 10 minutes googling for keywords like "ncftp",
"password", "bug", "ftp://user@pass -wget" (lest you get 100 tutorials
on how to use 'wget' with FTP urls :) ), etc.

No luck so far. :^(

I tried that, and didn't get much useful debuggng info. :^)

  $ ncftp
  ncftp> debug
  ncftp> open ftp://user:pass@ftp.server.com

  [server details]

Ah-hah!  Someone, somewhere, is using "%" as an escape character!

Based on the debug attempt above (where I was doing the "open" command
within NcFTP client, and not on the command-line in the Bash shell),
it looks like NcFTP itself is doing this.

I'll have to see if I can get around those "%" characters by
escaping them myself, somehow.

Thanks! :) :)  Good ol' strace. :)

-bash: reportbug: command not found
