That's probably not related to Lifelog or Smartband, but to a bad GPS fix. It appears that when in a building reception is changed in such a way that enough satellites are seen and valid results produced, but none that make any sense to the user.
For example when sitting in my office (in germany) having GPS running it happens occasionally that my GPS position tells me that I'm in india. This is nothing flakey, position remains stable for quite some time! I can use Google Maps to get a look at the area, or even launch Ingress (yes, so far I resisted the temptation of hacking a few portals). ;)
Also, I noticed random GPS position movements several times, and firing up "GPS Status" shows that GPS is to blame.
