> I'm also getting further errors:

Yes I was just about to mail with the same problems :). FWIW here are the log messages I get

```
Tramp: Checking ‘vc-registered’ for /ssh:<ssh login>:/home/jacob/tmp.c...done
Tramp: Encoding local file ‘/var/folders/9w/7dlszmmn6q1gd5yf3r9n79bc0000gn/T/tramp.luvXdR.c’ using ‘base64-encode-region’...done
Tramp: Decoding remote file ‘/ssh:<ssh login>:/home/jacob/tmp.c’ using ‘base64 -d -i >%s’...done
Wrong type argument: "Wrong type argument", "number-or-marker-p nil"
tramp-error: Wrong type argument: "number-or-marker-p nil”
```

Perhaps related but I also get this rather strange message on C-g:

```
Quit: “"
```

I have not been able to reliably reproduce it unfortunately, but I believe it occurs if you hit C-g after saving the remote buffer.

Glad someone else took the time to bisect, I was not looking forward to it...
