Only a problem when GMapUIOptions.controls.menumaptypecontrol is set.

Using MapUIOptions.controls.maptypecontrol works.

Does the problem also occur if you get rid of the default UI, and just add a 
MenuMapTypeControl to the map by itself?

Apparently it's only a problem if added through GMapUIOptions:

Your 'bug' only happens when the height of the browser window is resized, not  when
the width of the brwoser window is resized.

I'm talking of this example page

http://www.kclsoftware.com/googlemaps/resizebug.html

I looked only very quickly over your script and I think there could be an error in
your css or in your script.

Try to put an alert after you define st.height:

 st.height = win_size.height;
 alert(st.height);
 
You will get an empty alert in every case. But I didn't look deeper, so I cannot tell
you the reason.

When the width of the window is resized, the size of the map does not change. In fact
in current version of the page that the given stripped down version is based on, I
explicitly set st.height to empty string so that the MapSearchResultsSide class takes
over with height: 100%.

Also the ONLY difference between http://www.kclsoftware.com/googlemaps/resizebug.html
and http://www.kclsoftware.com/googlemaps/resizebug2.html is how the map type control
is added:

Yes, you are right.
The bug is also reproducible in a very simple page when the width and/or height of
the map is defined in percents.  

After resizing the browser in any direction you even get the error when you click on
the map.

Addition: The bug only seems to happen when the map is small enough so that
setUIToDefault() will be built as MenuMapTypeControl().

As I said in http://code.google.com/p/gmaps-api-issues/issues/detail?id=1219#c1 it
also occurs when you use setUI(customUI) where customUI.controls.menumaptypecontrol
is true. 

If MenuMapTypeControl is manually added. There is no error.

Thanks, I've reported it to the team.

Changing status of "Accepted" issues to "Acknowledged", to clarify their 
state.

We may not be able to resolve all bugs or fulfill all feature requests, but 
we do thank you for filing them, and we will continually revisit all 
acknowledged issues and evaluate their feasibility. Thanks!

There was some confusion with the change from the "Accepted" status to the 
"Acknowledged" status, and some developers took that to mean that their bug 
was being downgraded. This was only a wording change, not a priority 
change. We are still working on fixing many bugs (particularly the 
regression bugs), so a fix for your bug may still be coming in the future.

After a discussion in the forum, we will now use "Confirmed" instead of 
"Acknowledged". This status indicates that we have verified the bug, 
reported it internally, and it is included in the list of bugs that we 
review each week (when determining what to fix next).
