Subject: kconfig: qconf: SIGSEGV when clicking outside edit area
Date: Thu, 29 Oct 2020 16:50:14 +0200	[thread overview]
Message-ID: <boris.20201029163302@codesynthesis.com> (raw)

After the recent qconf interface changes I've stumbled on SIGSEGV
when clicking anywhere outside an active edit area. To reproduce,
try to create a new configuration and edit a non-boot/tristate
option (int in my case) with a default value. Then, while having
the edit box active, click anywhere outside it.

The stack trace I get is as follows. This is with Qt 5.5.1. Let
me know if you need any other information.
