           Summary: Konsole crashes when attempting to save output to a
                    file
           Product: konsole
           Version: 16.08.1
          Platform: Compiled Sources
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: awilfox at adelielinux.org
  Target Milestone: ---

Application: konsole (16.08.1)
 (Compiled from sources)
Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.8.0-rc5-ciall x86_64

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

I was attempting to save the output of a terminal to a file.  I accidentally
typed into the "file type" box instead of the "file name" box.  I backspaced
and then went to the file name box.  I started to type a file name and when I
did, it crashed.

-- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
