Tramp and BusyBox problem?

[Mats Löfdahl]

I'm trying to connect with tramp to my NAS (a Synology CubeStation 407), 
which is running linux and BusyBox. Regular ssh works fine and when I 
try to connect from emacs it looks like everything is going fine through 
the tramp setting up procedure, until I get to the following point:

...
tramp: Testing remote command `/bin/ls' for -n...okay
tramp: Using remote command `/bin/ls' for getting directory listings
tramp: Sending the Perl script `tramp_file_attributes'...done.
tramp-handle-file-attributes: Wrong type argument: listp, if

Of course, I don't know if BusyBox is to blame here, it's just that it's 
the thing in my NAS that I know differs from the systems I usually 
connect to.

Any ideas?
