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

-- Information about the crash:
- What I was doing when the application crashed:opened konsole in /home/downloads/ (using dolphin) and then started pkgtool (slackware program) to install a program. The program installed and then returned to a prompt. When I closed out the konsole then the bug report tool popped up saying konsole had crashed. Was able to reproduce/get the same results. Right click in the downloads folder/select open terminal from the menu/type pkgtool at the prompt/install program/close out konsole by using the mouse and clicking the "x"/bug report pops up saying konsole crashed.

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