      Description

      An user of my PyQt-based browser reported a segfault when visiting http://docs.saltstack.com/en/latest/topics/tutorials/pillar.html (with a Debian Jessie running in VMWare).

      I couldn't reproduce it with any of these configurations:

      • Archlinux native
      • Windows 7 native
      • Windows 8 in Virtualbox
      • Debian Jessie in Virtualbox
      • Ubuntu Trusty in Virtualbox

      So this might be something specific to VMWare. He could reproduce it with Otter Browser and qutebrowser (my PyQt-based browser).
