The error some of these IE users are seeing is:
Webpage error details User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; GTB5; .NET CLR 1.1.4322; .NET CLR 2.0.50727) Timestamp: Sat, 18 Apr 2009 15:26:06 UTC

Google has confirmed the issue in the threads. Mike CH from Google said:
I wanted to update you on the "elem is null or not an object" error that some of you have been seeing. This is a recently introduced bug which only occurs on Internet Explorer when loading certain locations. Thanks to your (very!) helpful reports, we were able to quickly locate the problem. It's being treated as a priority fix and will hopefully be live shortly.
Workarounds for now include:
- Not using Internet Explorer - Using the link I provided above to open Maps
I assume a bug like this will be fixed pretty soon. I personally tried to replicate the issue on my PC, but was unable to.
