GTKMM: Adding Gtk::TextView member doesn't allow me to bring up the GUI anymore.

[jbu <jtb3f virginia edu>]

Hi all, 

I'm a GTKMM and C++ newb, so this may be a very stupid mistake.

My problem is that adding the line "Gtk::TextView textView;" to my header causes my GUI not to display anymore.   Without that line, it comes up fine.  Note, that I have not included my source in this email/post because I did not change anything in the source.  The only change is that one line to the header as well as its corresponding "#include <gtkmm/textview.h" include statement. The GUI  just no longer comes up.  The program terminates/returns immediately
without any error.  Also note that this compiles fine without warning. 

I am using eclipse to develop as well as gtkmm 2.4 and I have ubuntu's gtk2.x package installed.

Please help me out.  

Thanks,
jbu
