Report tab displays all white - worked last time (Aug 2016)

[Rufus]

Guncash reports don't display anymore; tab opens, screen is white. All
reports fail this way - saved and predesigned. Last time they worked was
Aug 3, last year. Got back in town and booted Suse 42.2 system, ran
updates; later when I opened GC, no reports. GC opened to the set of
tabs where I left it last Aug; no error messages anywhere I noticed; I
have made no changes to the data or the setup.

Appreciate any/all thoughts.

Thanks
