Application: ark (17.04.3)

Qt Version: 5.9.1
Frameworks Version: 5.37.0
Operating System: Linux 4.4.74-18.20-default x86_64
Distribution: "openSUSE Leap 42.2"

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

opened an attachment from an email (kmail) via ark containing just 3 files, no subdirs.
A click on the down-button on the "Extract" tool button and clicking on "Extract To..." crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: Ark (ark), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
