slow startup since 1.2.0, after 1.1.1 (F-Droid builds)

[kolAflash]

After updating from 1.1.1 (F-Droid build) to 1.2.0 (F-Droid build) the startup of WiFiKeyShare became very slow. With 1.2.0 there's nothing in the wifi list for about 13 seconds. With 1.1.1 the list loaded under 1 second.

I have ~100 wifis saved. Downgrading to 1.1.1 solves the problem immediately and the "My Wifi Passwords" app also works fine (but provides no QR codes, because of which I prefer WiFiKeyShare).

Here's some logcat output, generating while the app started.

Same here, I changed phones, connected to my home wifi network and installed Wifikeyshare, my single network appeared instantly (and alone) when I opened wifikeyshare. Then I imported all my saved networks (more than 100) and now it takes a long time to load the list.
