I would not call this reproducible as such in my experience. It is
quite common, though. It happens a few times a day when I use gschem.
Once I do try to setup the debug I will keep an eye out for crashes
and provide information when they happen. For the moment, some notable
moments where I have come to not be surprised when gschem crashes :

 - saving using F+S
 - manipulating a copied buffer with E + I, E + R
 - rapid changes in zoom level using the scroll wheel (though less
sure about this one)

In all instances, gschem offers to load backup on next startup which
is maybe 30 seconds behind the instant of the crash, so it is
'manageable'.
