Hello Luis;

Thanks for the query, and sorry for the delay.  Here is a cut-and-paste of what passes for a test-case.  Basically, I have an old symbolic link hanging about, which has ":0" at the end (the X11 display number?), and which further happens to be a symbolic link to yet another old file - they are presumably created by Linux' DCOP (although I am not familiar with the details)...  SBCL returns a (long) list of pathnames that includes both the symlink (with the ":0" in the pathname) and the pointed-to file.
