Now that I've tried adding that locally, it indeed what triggered the 
problem. It was a bug in 'project--git-submodules', which I've just 
fixed on master in commit 915b34d280.

I think file listing together with submodules should work fine now in 
your case. Not sure about the performance though: we use one process 
call per submodule, so the overhead might get noticeable with 42 of 
them. But please give it a try.
