I think that's the same error I reported earlier today:
A bug in pyxattr < 0.2.2 causes listxattr to report broken values when
called on symlinks, like the ones shown in my debugger output:
-------------------- 8< --------------------
(Pdb) rp.path
'/usr/share/man/man1/lpq.1.gz'
(Pdb) rp.issym()
True
(Pdb) rp.conn.xattr.listxattr(rp.path, rp.issym())
('', '', '', '', '\xff\xff\xff\xff', '', '', '', ')', '', '',
'\xdcd\x9f\t\x04\xea\x7f\t\xdcT\xf2\t')
(Pdb) rp.conn.xattr.listxattr(rp.path, False)
()
-------------------- 8< --------------------
The empty strings above cause the '[Errno 34] Numerical result out of
range' errors when used with getxattr() later in read_from_rp.
