[Pedro A. Aranda]

1.- Open zip archive in remote machine using TRAMP
2.- Modify archive member
3.- Try to save with Ctrl-x Ctrl-s

Backtrace:

Debugger entered--Lisp error: (wrong-type-argument stringp nil)

#f(compiled-function (archive) #<bytecode -0x3085e9518db29cc>))

Will work w/o problems on locally edited archive
