SDL_VIDEODRIVER= gibberish

SUMMARY
Some strings followed by equals signs when input into krunner will cause the calculator runner to output garbage. (some will crash krunner entirely, see https://bugs.kde.org/show_bug.cgi?id=454130)

STEPS TO REPRODUCE
Type certain phrases followed by equals signs into krunner

OBSERVED RESULT
Gibberish from calculator krunner

EXPECTED RESULT
Calculator runner should probably not be parsing strings like this

Amazing.
Comment 3 Alexander Lohnau 2022-05-23 19:13:24 UTC 
I could not find an easy way to detect an error from evaluating the qalculate statement. Unless anyone has ideas, I will open an issue on their Github tracker.

See https://github.com/Qalculate/libqalculate/issues/442 for the code snippets.
I have only adjusted those to compile inside of the plugin.
