Bug#1137518: xserver-xspice: Segfault due to incorrect parsing of default values

Package: xserver-xspice
Version: 0.1.6-1.1
Severity: grave
Justification: renders package unusable
Tags: patch upstream

As reported upstream:

https://gitlab.freedesktop.org/xorg/driver/xf86-video-qxl/-/work_items?show=eyJpaWQiOiIxNiIsImZ1bGxfcGF0aCI6InhvcmcvZHJpdmVyL3hmODYtdmlkZW8tcXhsIiwiaWQiOjU2NTg2fQ%3D%3D

Since the original report is 4 years old, it may not get fixed
upstream anytime soon, so at least in the meantime you may want to
fix it in Debian:
