Okay, I've been at this for hours, with little progress. The problem has
something to do with reference counting on the editor in the
GridCellAttr. I've been able to delay the segfault until another cell is
selected by adding a editor.IncRef() call just before setting it to the
CellAttr, but can't get further than that.
Tomorrow out of curiosity I'll do regression testing, but I'm pretty
sure I'll find that this was a problem before my recent grid changes.
Google turned up a discussion of a similar problem that was introduced
in wxWidgets 2.6.1 that didn't exist in 2.6.0 and which has been fixed
in CVS. I'm hoping that turns out to be the culprit, in which case we
wait for the fix.
Turns out we aren't really using the renderers and editors in the
intended fashion: we should be instantiating one of each type and then
cloning or IncRef'ing that single instance instead of always
instantiating new instances each time. But that probably isn't the root
of the problem...
