backtrace

I am unable to calibrate my Wacom Cintiq 13HD tablet within the Gnome Control Center. Clicking on "Calibrate.." will result in a segfault.

While creating the backtrace I also found that a file seems to be missing: clutter-master-clock.c

Comment 2 Stas Fomin 2015-09-06 00:06:48 UTC 
This problem occurs with all Wacom tablets, I see it on several models of laptops with touchscreen (HP Elitebook 2730p/2740p…, etc).

It crashed in "_clutter_master_clock_start_running"
  in "CLUTTER_IS_MASTER_CLOCK (master_clock)".

I tried clutter-1.22.0, 1.22.4, 1.23.2, 1.23.4 — same problem.

The problem doesn't happen with wacom bamboo.

I suspect it only affects cintiqs with an integrated display and laptop touchscreens.
Comment 4 Bastien Nocera 2015-09-09 09:46:15 UTC 
In which thread did it actually die? You used gdb, so this should show before you request a backtrace. Do you see any errors on the command-line? The full gdb session would help root cause this problem.

> In which thread did it actually die? 

Thread 5. The thread that Rui highlighted in comment 1. That's clear from a backtrace without debugging symbols which the reporter had originally posted at https://bugs.gentoo.org/show_bug.cgi?id=553428

I sincerely apologize - I can't count. I meant to say thread 1.

>The problem doesn't happen with wacom bamboo

Of course, the bug considered only screen tablets because non-screen tablets not need to calibrate (no such button, there are another button "map to screen").

Just for illustration — small screencast of the bug

If someone understand all these GTK stuff — please, contact me, I can provide remote access (VNC/SSH) to such laptop.

I want no bounty, but for the life of me I can't reproduce, nor am able from the backtrace to find out the signal handler where this happens. It has to be a clutter or clutter-gtk bug because g-c-c doesn't get any close to the master clock, but that's as much as I know.

If you're willing to offer VNC/SSH access, please contact me through my bz address, I'm definitely interested to find out what's going on.

After a brief debugging session, the system I was granted access for testing had a clutter 1.23.4 package installed, just building clutter master (1.24.3 atm) and running the installed gnome-control-center with modified LD_LIBRARY_PATH was enough to get rid of the crash.

Given the installed Clutter was unstable, and the current stable fixes the bug, I didn't bother much in bisecting. Given this isn't seen in f22, I'd dare say Clutter 1.22.x doesn't have this bug.

I'm closing as FIXED, even though I can't put a commit ID here. Stas, feel free to drop any insight or reopen if there's anything left addressing around this crash.
