SUMMARY

I was using a Fedora 34 KDE Plasma installation with Plasma 5.21.0 on Wayland. I updated the system with sudo dnf upgrade. The update included R-4.0.4-1.fc34.x86_64 and rkward-0.7.2-2.fc34.x86_64. I rebooted and logged in to Plasma on Wayland. I started RKWard, and its wizard suggested that I install R2Html and rmarkdown. I installed those packages with their ~15 dependencies to /usr/lib64/R/library as root. The installation completed succesfully. I clicked Done in the installation window. RKWard aborted right after that. The functions at the top of the stack seem to indicate some sort of memory management error such as a bad allocation in frames 8-9. Some of those functions were from libstdc++-debuginfo-11.0.0-0.19.fc34 and qt5-qtbase-5.15.2-13.fc34.

Application: RKWard (rkward), signal: Aborted

STEPS TO REPRODUCE
1. Boot a Fedora 34 KDE Plasma installation updated to 2021-2-16. 
2. Install R-4.0.4-1.fc34.x86_64 and rkward-0.7.2-2.fc34.x86_64 
2. update the system with sudo dnf upgrade 
4. Reboot
5. log in to Plasma on Wayland
6. start RKWard
7. In the RKWard wizard, install R2Html and rmarkdown to /usr/lib64/R/library as root. 
8. click Done in the installation window. 

OBSERVED RESULT
RKWard aborted after installing recommended packages

EXPECTED RESULT
RKWard wouldn't crash.
