Well, that's easy enough to check - I installed Lepton EDA, restored the 
theme files to their original state, and sure enough, lepton-schematic 
also logs huge numbers of the identical error messages. The only 
difference is that lepton-schematic keeps silent while this happens 
instead of popping up error messages all the time like gschem does.

After again commenting out those lines referring to the separator bar, 
things work fine again - albeit with a CLI warning that the separator 
bar image appears to be missing:

$ lepton-schematic
/usr/share/themes/Breeze/gtk-2.0/widgets/menu:42: Background image 
options specified without filename
/usr/share/themes/Breeze/gtk-2.0/widgets/menu:275: Background image 
options specified without filename

But this isn't all that bad, as this only happens when starting the 
application.

I also looked at the offending image line-h.png (see attached, normally 
residing in /usr/share/themes/Breeze/assets), but I can't yet see why 
this would cause problems. Maybe the error messages provide a clue:

    borders don't fit within the image
    invalid source position for vertical gradient

Perhaps it's an idea to find the developers of this Breeze theme, and 
tell them about it. There are probably other applications that somehow 
suffer from this problem.

Regards,

Richard

      I'm not too convinced of this claim (lepton-netlist doesn't really
