Control: tags -1 + patch upstream fixed-upstream
Hello Mladen Mijatov, dear Maintainer,
the first frames would be translated by addr2line to following [1].
This looks like the crash is caused by an invalid pointer pself/self
in function cc_display_mode_dbus_is_supported_scale [112].
This pointer is retrieved by cc_display_monitor_get_mode in [399].
That led me to this upstream bug [2] which got
already fixed in [3]. Either of the upstream tags 3.34.2 or 3.35.2
contains that patch.
Kind regards,
Bernhard
