Taking a photo not working / xenial

...or alternatively device just reboots when starting camera-app. Currently qtubuntu-camera no-change rebuild is done in the PPA to try out if there's any change, but no change.

I'm now testing on xenial, since it's bootable (see QtTesting page), and I'm just getting a reboot when starting camera-app, regardless of if using the no-change rebuild of cameraplugin-aal or not.

The only suspicious line in the log (when starting from command line) is "QObject::connect: No such slot AalImageCaptureControl::onPreviewReady()".

Note that normal video playback was successfully fixed with https://code.launchpad.net/~timo-jyrinki/qtvideo-node/port_to_qt56/+merge/292369

I'm out of ideas since I'm not finding anything in the logs when the reboot happens.

The crash might be the general kernel crash bug #1551811 but I can't figure out how to get past it. But it's kernel crash indeed.

Back when it was opening the camera app, the problem was that the take picture button was disabled, but viewfinder was showing image fine.

This kernel crash seems to refer to camera-app + kernel v4l interface though instead of graphics driver directly like in bug #1551811, so maybe it's different.

The kernel crash issue seems to be there on xenial with both Qt 5.5 and Qt 5.6.

It may be possible to continue debugging the picture taking issue separately with the vivid Qt 5.6 silo, but Qt 5.6 will only land to xenial.

Updated the description a bit now that I got my krillin into development use. So the camera viewfinder is working but the original report stands that the "take photo" button is dimmed for some reason.

This bug was fixed in the package camera-app - 3.0.0+16.10.20160607-0ubuntu1
