Confirmed that the issue no longer happens on master, thanks.

1. Would it make sense to backport this patch onto the release branch?
The bug is annoying, and the fix seems trivial.
2. There's more suspicious code in the legacy backend that assumes
that magic or quoted filenames don't exist, is there a long-term plan
to tackle this? ("Deleting the legacy backend" might be a viable
long-term plan.)
