Regression: Camera is crashing when app has no Audio permission

[Michael Zanetti]

Some apps use the camera, like uTorch, Tagger, Authenticator but they do not actually take pictures. However, on OTA-10.1 they all started crashing because of this:

Setting media to: QUrl( "file:///system/media/audio/ui/camera_click.ogg" )
mpris.Player.Error.InsufficientAppArmorPermissions: Warning: Failed to authenticate necessary apparmor permissions to open uri: Client is not allowed to access: file:///system/media/audio/ui/camera_click.ogg

The camera backend should not crash if can't play the audio.

I too am experiencing issues with these three applications - Tagger and uTorch worked fine for me under OTA-9 (I hadn't tried Authenticator yet)...

It appears to be some sort of issue with granting the permissions... These applications stopped working since upgrade to OTA-10.1, but after a reboot/restart, all three asked for access to the camera (which they did not do previously), then they seem to work fine.

uTorch and Tagger previously had access to the camera, but apparently I needed to grant this again since the upgrade to OTA-10.1.

Hope this information helps with the fault-finding...
