Bug 441763

Application: rkward (0.7.2)

Qt Version: 5.15.2
Frameworks Version: 5.85.0
Operating System: Linux 5.13.12-2-default x86_64
Windowing System: X11
Drkonqi Version: 5.22.4
Distribution: openSUSE Tumbleweed

-- Information about the crash:
- What I was doing when the application crashed:
- Started RKWard on openSUSE Tumbleweed with KDE Plasma
- Checked installation, started download and installation of R package "rmarkdown" and dependencies
- after successful download and installation of R packages, the application crashes when hitting button "Done" (happened repeatedly several times now), however the app RKWard can be started again and seems to run fine

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: RKWard (rkward), signal: Segmentation fault
