That's a bug.

(A corrected version would also try "URL guessing" in that cases, i.e.
DNS lookup for jfdfjsl, etc. (dependent on configuration).)

A -trace might be also helpful, look for lines like
   STARTFILE 'jfdfjsl' is not a URL
   Converted 'jfdfjsl' to '/some/path/jfdfjsl'
   Can't stat() or fopen() '/some/path/jfdfjsl'

If you want just the two-line fix from my patch backported to 2.8.2,

than the "released" version, esp. if you don't ./configure in the newest /

If you stick with 2.8.2, apply at least the patch in

problems are fixed there, see above.)
