You can't do this, out is going to be freed after the if, so data will point to freed data.

More ore less the same here, because the CString returned by utf8() is a temporary.

And we don't want to convert to utf8 twice either.

You can use g_file_replace_contents_async(), instead of doing this synchronously.

I literally copied this from the non-remote implementation.

I missed it there, let's fix that first then.
