GladeVCP panel fails to launch intermittently

My GladeVCP panel fails to launch intermittently. The only errors that are found in the report are:
GladeVCP.QTVCP.QT_ISTAT][^[[33mWARNING^[[0m]  INI Parsing Error, No MIN_SPINDLE_0_OVERRIDE Entry in DISPLAY, Using: 0.5 (qt_istat.py:532)
**** GLADE VCP ERROR:    With xml file: crosshair_panel.glade : 'gi.repository.Gtk' object has no attribute 'glade'

and:

crosshair_panel.hal:7: Pin 'crosshair_panel.crosshair-ctl-active' does not exist

The second error is thrown because the panel fails to launch.  The reference to the pin is in my postgui_hal file.

How do I diagnose and repair this issue.

Regards,
