Facebook app freezes on spinner after login

[Andrea Bernabei]

Krillin, rc-proposed, r338

Here's what happened:
1) Flashed rc-proposed r338
2) Connected to wifi
3) Opened facebook webapp, login page launched
4) I put login and password, and the 2FA page loaded
5) I switched to system settings and tried adding an Ubuntu One account, but failed, tapping on Ubuntu One did nothing
6) After a while, I went back to Facebook webapp, and typed the 2FA code
7) chose save/notsave browser, and finished the login process
8) Login page closed and the app froze on a blank page with a frozen spinner in the middle

a few logs:

Hi Andrea, do you think you could reproduce this again?
There are a couple of thingsI need to know:

1) before reproducing the bug, please have this command running in a terminal:

   OAU_LOGGING_LEVEL=2 OAU_DAEMON_TIMEOUT=9999 online-accounts-service

   and attach the logs from this command into the bug (replace any tokens with XXX)

2) Please pay attention to page transitions: do you see the account window disappear by sliding into the bottom of the screen before the application gets stuck?

I took the time and flashed another krillin, but I could not reproduce the bug there, unfortunately

[Andrea Bernabei (faenil)]

the middle-of-page spinner is part of the account window, so I think it froze before the account window moved to the bottom
