[Bug 1480877] Re: Access points' "PropertiesChanged" dbus signals freeze UI on mobile devices

 

1) syslog attached

2) Yes it thinks it is connected to an access point which doesn't
actually exist in the office (it's only available at home). The rest of
the access points detected in the network indicator are up to date
though. To sum up: it thinks it's connected to an access point that
doesn't actually exist where I am now, but the rest of the networks it
shows are correct.

3)  yes

4) I can't think of any change

Title:
  Access points' "PropertiesChanged" dbus signals freeze UI on mobile
  devices

Status in indicator-network package in Ubuntu:
  New
Status in network-manager package in Ubuntu:
  Incomplete

Bug description:
  Krillin, rc-proposed, r83

  
  DESCRIPTION:
  I've been trying to track down the cause of the occasional UI freezes on my Krillin device, and I noticed that whenever the UI freezes for 2-4 seconds, I get a burst of "PropertiesChanged" signals in dbus-monitor

  Here's a log of what's shown in dbus-monitor:
  http://pastebin.ubuntu.com/11992322/

  I'd guess the problem is in the code that actually catches the signals
  and acts accordingly.

  HOW TO REPRODUCE: 
  1) Move to a place where many wifi hotspots are available
  2) Connect the device via USB and run "phablet-shell" and then "dbus-monitor"
  3) Use the device while keeping an eye on dbus-monitor output
