Combo signal problem

["Frank R. Larsen" <gobo gimle nu>]

Hi,

I'm using a combo-list where I call a function every time the selection 
is changed. I use the "selection-changed" signal to do this, and this 
works mostly fine, except that when I select an entry the signal-handler 
is called 4 times.

Since my signal handler connects to a MySQL database to fetch information 
this is wasting resources.

Is there a practical way to avoid the 3 extra calls, or do I have to put 
in a  check to see whether the signal was just done with the same data?
