version custom: 20160324--36-54-vivid

Steps to reproduce:
1. Connected to an available AP
2. Enable Flight Mode from network indicator, both Cellular data and wifi are disabled
3. Enable wifi, wifi reconnected and listing the available AP
4. Disabled wifi again, wifi disabled and the available AP list disappears
5. Disable Flight Mode

Actual results:
The wifi toggle is switched to 'On', but no available AP listed, network indicator showing the state of Cellular data connection.
If manual disable wifi then enable it again, it works normally.
Not sure if it's the same root cause of bug #1560793, though the reproduce steps are a bit different.

network-manager 0.9.10.0-4ubuntu15.1.11

@Evan: I suspect the problem is similar. However Tony is currently working on a big overhaul of the NetworkManager stack to bring us back in par with the upcoming 1.2 upstream release which will have some fundamental changes of how the whole scan management is implemented. There is a good chance that that will improve this bug too. Lets wait until that big change lands and then verify again that this bug still exists or not. We don't want to put much more time into the 0.9 release we have currently on Touch with 1.2 being very close.

However can you please attach /var/log/syslog and all other log files below /var/log so that we can rule out other things?

Hey, Simon,

Thanks for your quick reply, attached the syslog and all other logs under /var/log/, fyi.
