Detailed Description:
-----------------------------
I filed this as a wayland bug because the segfault happens in wayland-util.c
(which is in the wayland git)
Special notes:
* Run ALL the programs in "Steps to Reproduce"
* This is only reproducible with Weston running under X
* I can only reproduce this when an EFL program is running
Steps to Reproduce:
----------------------------
1. Download/Install Wayland, Weston, and EFL
2. Download/Install the VKB code from openismus (here:
https://github.com/openismus/ecore-imf-wayland)
3. Execute the following:
---Terminal 1----
$ ./weston
---Terminal 2----
$ ./clients/keyboard &
$ ELM_ENGINE=wayland_shm ECORE_IMF_MODULE=wayland ./bin/elementary_test
4. Click outside of the Weston window in X (say to your terminal) and allow
Weston to go to sleep.
5. Click back inside the Weston window (avoiding the unlock button) and then
click back outside to your terminal.
6. You should now see the segfault.
I have tried to reproduce this bug with just the keyboard (doesn't happen),
just EFL (doesn't happen), and using they keyboard on the editor client
(doesn't happen). I cannot reproduce this bug in DRM mode. It's caused by some
strange interaction between all the components (EFL, virtual keyboard, and
Wayland/Weston in X mode)
I asked around on #wayland and it was decided to bug this on fd.o.
I am going to attach a GDB backtrace and a valgrind log.
Good luck.
