Odd differences between F8.i386 and F8.x86_64

[Alexander Volovics]

When starting the scanner program 'vuescan' (32 bits) in an xterm
under F8.x86_64 I get the following:

[awol at localhost scan]$ ./vuescan
Gtk-Message: Failed to load module "gnomebreakpad": libgnomebreakpad.so:
cannot open shared object file: No such file or directory
(vuescan:3154): Gtk-WARNING **: Unable to locate theme engine in
module_path: "nodoka",

However vuescan seems to function OK qua scanning and file
manipulation tool (Though the GUI seems to be a bit 'shaky'
But maybe I am imagining things)

When starting vuescan under F8.i386 these messages don't appear.

Do these 'gtk' warnings indicate problems that might
appear under certain conditions or can they safely be
ignored.
