Init variable Location jams

[jmu]

The issue started happening recently (2 days ago?): Init Variable Location action fails to retrieve the location - something that worked just fine few days ago.
After setting the timeout, the log shows following:

Any idea where the issue might be?

Tried the old method: restarted the phone - and it seemed to help
I also tried restarting the app, but it did no difference.

Not sure if this is a device issue, but the same problem seems to occur every one or two days: location initialization fails.
Restarting the phone fixes the issue.

Or could it be something to do with the Automagic? I'm using Automagic to initialize location every time I open the Foursquare (something the 4sq should do by itself!)
