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.

I cannot reproduce this problem.


For example,

I visited "General setup" -> "Default hostname".

I double-clicked "(none)", then
the edit box was activated.

I clicked outside of the edit box,
and the edit box got deactivated.
I saw no problem.

My Qt version 5.12.8

Yes, I just tried that and I cannot reproduce it this way either. No
can I reproduce it with a minimal example with just one int option.
The attached Kconfig (from a "Hello, World" example I am writing),
however, reproduces it for me reliably:

$ rm .config
$ ENABLE_FANCY=y .../qconf Kconfig

Then, in the "Fancy options" select "Name fallback" and inside double
click on "Max times to ask for name" to activate the edit box. After
that, clicking anywhere outside of this edit box causes a SIGSEGV for
me. Can you try that?
