Detecting value change in GtkCombo

[Keith Maika <keithm aoeex com>]

Hello,

I'm making an application similar to WinSCP using GTK+-2.0  I have a 
tree view that will list all the files and directories in the working 
directory.  The working directory is displayied in a toolbar above the 
tree view using GtkCombo widget.  I'd like to be able to be able to 
change the working directory by either typing in another path in the 
entry of that combo, or select a parent directory from the drop-down 
list.  I've got it working by typing in an entry, but I cant get it to 
let me select one.  I've tried connecting the list inside the combo to 
the select-child and selection-changed signals and I'm able to get the 
selected value, but my application seg faults when I do that.  I'm 
thinking the reason behind the seg-fault is because I change the 
drop-down list inside of the selection-changed handler, but I can't 
think of any other way to do this.  I just recently tried the hide event 
but that doesn't even fire the signal handler function.

Does anyone have an suggestions on how to get notified when an item in a 
GtkCombo has been selected?  If you need/want to see what I have so far, 
you can get the source code from my site at:
