net-mail/gnubiff-2.2.15-r2 works perfectly with x11-drivers/nvidia-drivers up to 361.28, but on all more recent versions that I have tried (for 4.6 kernels), gnubiff SEGVs on launch UNLESS started with --nogui. Despite rebuilding net-mail/gnubiff with USE=debug I have been unable to determine the cause of the SEGV, except that it's clearly some kind of rendering issue. The SEGV happens regardless of whether a valid configuration file is present or not. Reproducible: Always Steps to Reproduce: 1. Happens every time. Even a simple 'gnubiff -v' will do it, and even with -v, --nogui prevents it. babylon5:alaric:~:11 $ gnubiff --nogui -v gnubiff version 2.2.15 CVS babylon5:alaric:~:12 $ gnubiff -v Segmentation fault
