In which of these areas are you experiencing a problem?

Theme

Expected behavior

Theme pull should only pull changed files from remote

Actual behavior

Occasionally, theme pull pulls existing files as an empty string; these need to be caught and disregarded. There doesn't seem to be any rhyme or reason to which files are pulled as empty: it's inconsistent in both frequency and the files which are pulled as empty. It's impossible to replicate in any meaningful way, but it's happened in more than one store over the last few days.

Verbose output

No error actually logged - just the change indicating that a file is now empty.
