Description

I've been fuzzing terminology and thus it spends its CPU time creating a window and closing it after processing some small input.
I had the attached backtrace.
I'm using efl from fc3c8a3296e, elementary from 371eb00ecb22434 and enlightenment from a524d165bcdc09a0.

I have been trying to track this one down for some time. Do you have a reliable way to reproduce it?

I use this version of terminology: https://git.enlightenment.org/apps/terminology.git/log/?h=devs/billiob/fuzz
It only works for fuzzing.
Then I can reproduce it like that: while [ 42 ]; do cat afl/in/colors_fonts | src/bin/terminology; done

@billiob I <3 your 100% functional reproduction case.
