[Python-modules-team] Bug#861680: python3-cairocffi: qtile crash with xcb problem

[Vaclav Ovsik]

Package: python3-cairocffi
Version: 0.7.2-2
Severity: normal

Dear Maintainer,
today I did an upgrade to this version of python3-cairocffi, but Qtile
WM stopped working. My .xsession-errors file ends with:

  Qtile crashed during startup
  Traceback (most recent call last):
    File "/usr/lib/python3/dist-packages/libqtile/scripts/qtile.py", line 116, in make_qtile

      p = cairo.cairo_xcb_surface_create(
  AttributeError: cffi library 'libcairo.so.2' has no function, constant or global variable named 'cairo_xcb_surface_create'
  
Probably the dropped dependency mentioned in changelog.
Qtile works again after downgrade back to 0.7.2-1.
Thanks
