[Eric] Seg Fault On Opening Dialog Box

[Helen Ready]

Thanks, Detlev, I will try the route of building all related packages from
source.  Help me to understand which package (PyQt, QScin, Sip, Qt) in the
chain from Eric IDE to the x11 might be the offender... my uneducated guess
is it's the Qt program when it attempts to open a dialog box with Gnome's
GTK API (due to the "*Gtk-WARNING **: Invalid input string") *?

I ran across some forums where they mentioned that a GTK warning can arise
from an outdated version of Gnome.  CentOS is build for stability and
unfortunately that means Gnome 3.14.4 is the most recent version I have
installed and is available in the standard repository.
