Ken,

I just tried this with GRASS 6.5 svn, which has an identical TclTk GUI  
as the release branch currently. I added bugsites to the layer manager  
and clicked show attribute data and it shows the same information as  
you get in the terminal.

Perhaps, there is some problem with db.select that has been fixed  
after 6.4rc3.
