Not at a glance. But the key to this mystery is most probably in your
customizations. Some code which probably runs off a timer or some X
event does something that directly or indirectly resets the variable
in that buffer. Maybe you have some code which directly or indirectly
calls kill-all-local-variables, for example. Or something else to
that effect.
I am still trying to find out what is doing that if something is doing that. Unfortunately no message statement inserted anywhere in my native linum enabling code is getting executed when this anomaly happens.
You could add logging to your functions that turn off the line
numbers, and see what's in the log when this happens.
None of those message statements gets triggered.
I have a feeling that this is happening due to some state change at system/GTK2 level.. because no messages in elisp are catching the line number toggling, and this happens when I move the focus out of the VNC viewer window to Windows. When I return to the VNC viewer and click on the window with the missing line numbers, they show up magically.
You would have a better idea if there are any hooks in display engine that get affected by GTK..
