[Pkg-electronics-devel] Bug#882934: pcb: Segfault on window operations

[Joe Rowan]

Package: pcb
Version: 1:4.0.2-4
Severity: grave
Justification: renders package unusable

Used PCB for the first time since early June, so I don't know when this problem began. Most movement or closing of program windows causes a segfault.
Here are the last few, in case there is anything useful in the numbers;

I tried completely reinstalling, no change.

I tried removing pcb-gtk and installing pcb-lesstif. The program is now stable, but I've used the GTK version for years, and I don't think I can get used to the Lesstif version.
This appears to be a GTK problem of some kind, but nobody else seems to have it. 
What can I try to provide further information?
