SUMMARY Version 0.7.1 STEPS TO REPRODUCE 1. make "correlation matrix plot" or calculate "descriptive stats" and submit 2. click "Run Again" in the output.html window 3. click on "code preview" 4. move your mouse into the code preview window and crash Note: It does not crash until you move your mouse into the code preview window. OBSERVED RESULT Crash EXPECTED RESULT No crash SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: plasma 5 on Fedora 31 (available in About System) KDE Plasma Version: 5.17.5 KDE Frameworks Version: 5.68.0 Qt Version: 5.13.2 ADDITIONAL INFORMATION
On a different linux box running Ubuntu 20.04, with everything else the same, I cannot reproduce the error.
Thanks for reporting. One the first machine, the problem _is_ reproducible? Every time? I assume, you did not get a backtrace? Could you 1. install gdb 2. run "gdb rkward" 3. in the gdb console, enter "start" then "cont" 4. reproduce the problem 5. in the gdb console, enter "thread apply all bt" 6. copy and paste the result into this ticket. Thanks!
Yes, it is 100% reproducible. Thank you for letting me know what to do. Here is the output from the backtrace...

Thanks! With that info the crash was easy to track down, and fixed in the development version. The difference between your two systems is likely that on one you set RKWard to focus-follows-mouse window activation behavior, while you left the other at click to focus (Settings->Configure RKWard->General, bottom of page).
Thank you for fixing this so easily! Indeed, I changed the focus setting and it won't crash if set for click to focus.
