The dconf denial should be harmless, unless you adjsted your app to use gsettings (you shouldn't, gsettings isn't currently supported in the SDK).
/run/user/32011/confined/com.ubuntu.developer.daker.rad-io.TJ3229 is not the correct path though. It seems like something isn't evaluating TMPDIR correctly. TMPDIR should be set to /run/user/32011/confined/com.ubuntu.developer.daker.rad-io. Can you give the value of TMPDIR when your app is running?
