Description

Attachment: usage.png

If you open the usage app, then the browser and then the app again no information is displayed.
Test link: https://github.com/mozilla-b2g/gaia/blob/master/tests/python/gaia-ui-tests/gaiatest/tests/functional/cost_control/test_cost_control_reset_wifi.py

This issue can be reproduced with both manual and automated testing.
Local reproduction rate: 5 out of 5. I could reproduce this on both 319MB and 512MB devices.

While running the automated test, all of the runs after the first one end with a crash:

3. disable mobile usage and enable wifi usage
4. tap homescreen button
5. open browser and navigate to a page, wait for a few seconds
6. tap homescreen button

Comment 2

[Viorela Ioia [:viorela]]

The issue is reproducible on latest v2.1 too, manually, by following STR from comment 0, and also by running the automated test: https://github.com/mozilla-b2g/gaia/blob/master/tests/python/gaia-ui-tests/gaiatest/tests/functional/cost_control/test_cost_control_reset_wifi.py
but I'm not getting any crash after running the test several times.
