Package: libva2
Version: 2.6.1-1
Severity: grave

Hi,

It seems that after a recent full-upgrade, querying certain render nodes fails,
crashing my program; it is easily reproducible using vainfo:

  gruessi:~> vainfo --display drm --device /dev/dri/renderD129
  libva info: VA-API version 1.6.0
  vainfo: VA-API version: 1.6 (libva 2.6.0)
  vainfo: Driver version: <unknown>
  zsh: segmentation fault  vainfo --display drm --device /dev/dri/renderD129

The crash is in

  Program received signal SIGSEGV, Segmentation fault.
  0x00007ffff7e254f2 in vaQueryConfigProfiles (dpy=0x55555555d2d0, profile_list=0x55555555dc10, 
      num_profiles=0x7fffffffe92c) at va.c:903

      at ../csu/libc-start.c:308
  #3  0x00005555555568aa in ?? ()

It seems that somehow, the device is opened but gets a NULL vtable:

  (gdb) print *ctx
  $2 = {pDriverData = 0x0, vtable = 0x0, vtable_glx = 0x0, vtable_egl = 0x0, vtable_tpi = 0x0, 
    native_dpy = 0x0, x11_screen = 0, version_major = 0, version_minor = 0, max_profiles = 0, 
    max_entrypoints = 0, max_attributes = 0, max_image_formats = 0, max_subpic_formats = 0, 
    max_display_attributes = 0, str_vendor = 0x0, handle = 0x0, drm_state = 0x55555555d2a0, glx = 0x0, 
    display_type = 49, vtable_wayland = 0x0, vtable_vpp = 0x0, override_driver_name = 0x0, 
    pDisplayContext = 0x55555555d2d0, error_callback = 0x7ffff7e23540 <va_driverErrorCallback>, 
    info_callback = 0x7ffff7e23560 <va_driverInfoCallback>, reserved = {0 <repeats 38 times>}}

I can query renderD128, which corresponds to my Intel iGPU just fine.
renderD129 corresponds to my RTX 2070:

  gruessi:~> cat /sys/class/drm/renderD129/device/vendor
  0x10de
  gruessi:~> cat /sys/class/drm/renderD129/device/device
  0x1f02
