Thanks for reply. I got something interesting:
1) Problem does not occur in the development snapshot
2) I anyway collected the backtrace via MinGW gdb. I can just take the development snapshot, but I think it might be interesting for you to know the reason:

Please also try setting w32-get-true-file-attributes to t before you
type "C-x C-f" to open a remote file.  Does that crash as well?
