            Bug ID: 364616
           Summary: konsole crashes while typing inside nano editor
           Product: konsole
           Version: 15.12.3
          Platform: Compiled Sources
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: orionbelt2 at gmail.com

Application: konsole (15.12.3)
 (Compiled from sources)
Qt Version: 5.5.1
Operating System: Linux 4.4.6-gentoo x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:

I was typing a message in the nano editor, called by a mutt session. This has
been happening since i was forced to switch to Plasma 5 a couple of weeks ago:
My konsole sessions die sooner or later while i type inside nano. I have not
been able to identify a specific sequence of characters before the crash. I
often switch between several keyboard layouts while typing, in case that may be
related.

Note that the crash always happens *while* i type something, never while i am
off doing something else. This is a difference from all the reported possibly
related bugs, and it is why i file it separately.

This is a show-stopper for me since konsole is my workhorse application, and
this bug takes it down along with all its tabs!

The crash can be reproduced every time.
