Title:
after clickpackage update app launches as white screen
Status in “unity8” package in Ubuntu:
Fix Released
Bug description:
Ubuntu-touch 14.04 on maguro r236
after updating an app (calculator in this case), lauches as a white screen.
This does not cause a general freeze. I am able to swipe the app-gone-white
back offscreen. At which point opened apps does not show it and i was not able
to swipe it back in again. app was killed apparently. I can however repeat the
behaviour consistently.
After a reboot however, this doesnt happen anymore. The app starts normaly.
I have in fact seen this a number of times over the past year on my
device: after updating, an app will launch as white screen. After
reboot, everything is fine. As far as a can remember it has happened
with a number of different apps.
/home/phablet/.cach/upstart show the calculator crash:

I also looked at /var/crash
but it doenst look to me as there is anything usefull there.
btw this sounds similar to:
https://bugs.launchpad.net/upstart-app-launch/+bug/1270975
by Alan Pope
but i will let others be the judge of that.
