Gtk-WARNING, How to fix ?

[Flavio Alberto Lopes Soares <flavio maqplas com br>]

Hello all,

I developing an application that uses 640 checkbuttons performing a 32 X 20 matrix using gtk1.2, recently in my Debian woody system I upgraded to Gnome2.2 and your libraries, and after this, when I open the window that has these checkbuttons (running my app from a xterm) I had these warnings : 

Gtk-WARNING **: gtk_widget_size_allocate(): attempt to allocate widget with width 65532 and height 19

I don't know if exists relantionship with this warning but when I compiling/linking my app I receive these message from gcc :

.
.
.
make[2]: Entering directory `/home/flavio/Projects/ihmserial/src'

/usr/bin/ld: warning: libgdk_imlib.so.1, needed by /usr/lib/libgnomeui.so, may conflict with libgdk_imlib.so.2
.

My application runs OK but I think these warning strange.
Someone knows what is this and how to fix this ?
I will be been thankful 

Success for all
