from http://curl.haxx.se/libcurl/c/libcurl-errors.html 21 is "quote" error... a bit weirdly named, but apparently when rm was broken around 2007 (per mailing list), same error popped up.
the command line example at the time was curl sftp://.../path/to/file.txt --quote rm Perhaps someone can correct me if that changed. someone appears to have solved related issue by doing url sftp://server/ and quoted command rm "/path/to/file.txt" http://curl.haxx.se/mail/lib-2012-05/0101.html good luck!
