Title:
scoperegistry uses 45% CPU after applying updates from the store,
draining battery quickly
Status in the base for Ubuntu mobile products:

Status in unity-scopes-api package in Ubuntu:

Bug description:
current build number: 44
device name: arale
channel: ubuntu-touch/rc-proposed/meizu.en
last update: 2015-07-02 07:10:44
version version: 44
version ubuntu: 20150702
version device: 20150608-6e66f3c
version custom: 20150602-731-5-32
Suddenly this morning, the battery started discharging very quickly,
'top' revealed that scoperegistry was using around 45% CPU steadily.
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
2207 phablet 20 0 377996 9576 6200 S 46,0 0,5 67:34.54 scoperegistry
Around the same time that the battery started dropping, I applied all the updates from the store, in the list of apps to update were:
- Terminal
- BBC Sport
- BBC
- Euronews
- Engadget
- Cnet
I pressed 'Update all' and waited until it's done then closed system-
settings.
There is no crash file corresponding to this event.
I reproduced it on ubuntu-touch/rc-proposed/bq-aquaris.en/krillin #55
