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,

Update: I uninstalled Glade and then reinstalled it. The issue still persists.

The errors thrown during launch not reads:

tool_mmap_user(): tool mmap not available
poll(): continuing without tool mmap data
gtk-builder-error-quark: crosshair_panel.glade:12:34 Invalid property: HAL_Table.n-rows (11)
**** GLADE VCP ERROR: With xml file: crosshair_panel.glade : 'gi.repository.Gtk' object has no attribute 'glade'

when launched from the panel from the command line:

$ gladevcp crosshair_panel.glade

Maybe I need to reinstall linuxcnc?

Regards,

I can't help you, but have a suggestion.
The "object has no attribute" is python's error and means "python can not finds", probably due bad path.
For me often helps to install python package in both ways, deb package and pip package.
