Hey Spencer!

Some things you can do to test in strict mode is to tail
/var/log/syslog, running your program, and check the apparmor denial you
probably get when acessing to some files/do some calls.
That would be a great hint for you on debugging this issue, and report a
bug if a new interface tweak is needed!

Remember that you won't be able to publish on the stable channel if your
snap is in devmode.

Cheers,
Didier
