APV won't open locally-stored PDFs

What steps will reproduce the problem?
1. When loading a PDF from a web link, it will download and APV (v0.4.0) will 
load it just fine.
2. Trying to open the *same* PDF files from /storage/emulated/0/Downloads using 
File Manager results in APV crashing instantly on opening.
3. APV's own built-in browser shows no files or folders under 
/storage/emulated/0 (even though there are many).

What version of the product are you using? On what operating system?

Running Android 4.4.2 on Nexus 5 (Cyanogenmod 11-M7)
APV v0.4.0 (I also tried downgrading to v0.3.x and had the same issue)

I'm a bit confused about whether this is a problem with APV itself, or some 
kind of permission problem. It's puzzling that APV can open downloaded PDFs 
directly, but can't open them from File Manager and can't browse to them itself.
