As Charles would say, please create a bugzilla report on this.  Good work 
tracing down the cause!  I expect it should be fairly easy to fix this, with 
this information.  I expect the solution will be to simply attach a call to 
the redisplay function called when overviews are refreshed, to the end of the 
group load function.  It seems that would solve the problem and is a 
perfectly logical and simple solution, from here.  Filing the bugzilla report 
will ensure the bug doesn't get lost, and I'm guessing the fix, if as simple 
as I'm thinking it should be, will likely be incorporated into the 0.14.1,tho 
it might not make the next beta version.  (I'm not sure where they are on the 
path to it, but I'm guessing it might be out shortly, as 0.14.0 has been out 
some time -- long enough for the customary "rest" after a stable release, so 
the next beta should be just around the corner, I'd guess.)
