Clicking on camera & microphone settings crashes app on mako & flo

[Michael Terry]

On latest RC-proposed (255?) on my mako.

I go to Settings, Privacy & Permissions, then click on Camera & Microphone. Get a crash or freeze each time I've tried it. (but no crash file?)

@Michael: anything of interest in the app’s log file? ($HOME/.cache/upstart/application-legacy-webbrowser-app-.log)

Can you still reproduce the issue? Unfortunately I don’t have a nexus 4, and the feature works well on my krillin and on my arale, so it might very well be a device-specific issue, in which case we’ll need someone with a device to look into it.

[Michael Terry (mterry)]

I can still reproduce. On two separate makos (both running rc-proposed, haven't tried OTA 9.1). Nothing at all is printed in the log when this happens. :(

Although this time, I saw a crash file being generated (and uploaded, though I don't see it in errors.u.c yet). So I'm attaching it. But it doesn't have a core dump or stack trace in it...

[Andrew Hayzen (ahayzen)]

I can confirm this issue on mako, therefore I have set this bug to confirmed.

Also when I go to a website that uses webrtc such as [0] I get the following output and then a crash, not sure if it is linked or a separate issue?
Received signal 4 <unknown> 0000b61138d8

FWIW the webrtc site [0] did used to work for the microphone on mako.

I am able to reproduce the crash on nexus 7 with the latest rc-proposed image.

Status changed to 'Confirmed' because the bug affects multiple users.

[Richard Somlói (ricsipontaz)]

Nexus 4, rc-proposed channel, the same issue.

libhybris/android related problem. Nothing with camera-app

[Simon Fels (morphis)]

We're clearly missing symbols in libcamera_compat_layer.so in the device tarball on the Android side but I don't have a clue yet why. A local build of the package we have in the overlay ppa show me that the symbols ends up in the .so. Doing a no-change rebuild in silo 38 (https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/landing-038/) now.

[Olivier Tilloy (osomon)]

The bug seems to be affecting frieza as well (just tested on the latest rc-proposed image). Would the changes to the android package fix it on that device too, by any chance?

[Simon Fels (morphis)]

@Olivier: No, the android package doesn't have any effect on frieza. But we've just merged an upgrade for platform-api/libhybris for frieza, which should fix the same problem. Alfonso will release a new image on rc-proposed with this change included later today.
