Description Egmont Koblinger 2015-11-01 22:37:19 UTC 
Set g-t profile to: "When command exits: Hold the terminal open"

Exit from the running command (shell). Press a key => segfault.

Broken by the smooth scroll patch.

Fix

(No clue why the smooth scroll patch triggered this segfault, it's obviously irrelevant.)

Damn, I didn't realize this was a bug in the work-in-progress patch of bug 755371.
