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.
