Mantis#2048. Thank you kindly, HomerHorwitz for a patch that: 

The attached patch (against r6075) fixes it for grid-mode. If the 
home-region isn't available, the stored regionHandle will be used 
to compute the region-coordinates of the home. This will be wrong 
if the home-region has moved, of course, but without the region 
being online we can't request the RegionInfo of it for finding out. 
Doing that (before the patch) and accessing the (null) RegionInfo 
led to a NullReferenceException, which prevented logging in to the 
last location.
