Description: Ubuntu 16.04.4 LTS
Release: 16.04

asavage@Ubuntu1:~$ apt-cache policy xosview
xosview:
  Installed: 1.17-2
  Candidate: 1.17-2

--------------------------------------
When adding this option to ~/.Xresources:

   xosview*RAID: True
(and running 'xrdb -merge ~/.Xresources' )

Invoking xosview causes segfault

   asavage@Ubuntu1:~$ xosview
   Segmentation fault (core dumped)

If I then edit ~/.Xresources to:

   xosview*RAID: False

then xosview runs.
