I am observing crash with following callstack. Is this known issue to
anyone here and fixed with latest version? How should one debug such
issues? Any inputs, comments or suggestion to debug and fix this issue
would be very helpful.
I am suspecting it is related to bug
https://bugs.freedesktop.org/show_bug.cgi?id=91273 but how to confirm
I am planing to test with wayland/weston/wayland-ivi-extension 1.11.0.
Use-case: This is with video playback and clicking on next menu for
next video multiple times.
We are using i.MX6 based target on linux 4.1 and following packages
with fbdev-backend and ivi-shell with ivi-controller.so.
In one configuration ILM (client and control apis are used directly)
in gui application while with other configuration there is central
controller (layer manager) for managinf view of gui. However with both
the configuration this is observed.
media playback framework: cinemo or gstreamer (with both the framework
we observed the crash) with wayland/ILM support.
