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.

I'm still seeing this segfault, even on commitid: weston (master) 0ea7333392c3afdbcd8f9194d51cee1e3f55178c wayland (master) 92ca1a0e800cf85e42699774b141ac5204d0f7c8 To reproduce use the same steps above. I will attach a new GDB BT but it says the same thing (wl_list_remove issue).

Pushed this to weston master: commit 82ec909b07654d7d2f2f93e1f025dbbc4e4b7ac8 Author: Jan Arne Petersen <jpetersen@openismus.com> Date: Mon Dec 3 15:36:02 2012 +0100 shell: Do not remove input panel layer when locked Do not remove the input panel layer from the layer list when the shell is locked in hide_input_panels(). https://bugs.freedesktop.org/show_bug.cgi?id=56543 Signed-off-by: Jan Arne Petersen <jpetersen@openismus.com>
I couldn't get the ecore-imf-wayland module to work again, I got it to compile and install but couldn't launch the elementary_test application using the module. Sent a detailed e-mail to Michael and Jan at openismus to fix the issue, it's happened because there have been large changed to the EFL tree and the ecore-imf-wayland repository needs to be updated.
Committed this fix from Jan: commit d1a5cd0088d4735f8633d021ac157a3c1d367321 Author: Jan Arne Petersen <jpetersen@openismus.com> Date: Mon Feb 11 15:10:11 2013 +0100 shell: Fix bug when input panel is shown twice Signed-off-by: Jan Arne Petersen <jpetersen@openismus.com> I haven't had time to try to reproduce this issue so I'm not sure if this fixes this bug.
I also now merged Jans remaining input method patches with a few more input-panel fixes. I'll close this now as resolved, re-open if verification fails.
Changing status to verified as fixed.
