Application: ark (17.04.3)
 (Compiled from sources)
Qt Version: 5.7.1
Frameworks Version: 5.37.0
Operating System: Linux 4.12.12-gentoo x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:
I tried to extract a file from a password-protected 7-zip archive, but accidentally entered the wrong password. Ark crashed on the second attempt as well (using a deliberately wrong password).

The crash can be reproduced every time.

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