Opened xterm, closed xterm. No crash.

Also your backtrace makes zero sense. _e_comp_object_setup() is only called during show, yet it's called here during hide. Adding some internals experts...

Which version of E? Which distro? Which versions of Wayland...?

As zmike said, the calls sequence doesn't make sense.

ApB added a comment.Jan 19 2016, 5:44 AM

Arch with everything standard (whatever comes from the repos) and E from git.

The thing is after building today i can't reproduce it anymore. :/

Magic fix.
