Description tmpod 2022-07-04 23:52:08 UTC 
SUMMARY
(KDE Crash Tool didn't seem to do anything after pressing the report button...)

KRunner's calculator doesn't seem to be able to handle fractional exponents, like 0.5, 1.2, freezing completely right as you type the first decimal character (after the dot).


STEPS TO REPRODUCE
1. Open KRunner
2. Type "123**0.5"

OBSERVED RESULT
The whole KRunner interface freezes, and is kept on top of everything else. Looking at htop shows that pretty much all threads are dead, with exception of one which remains sleeping.

EXPECTED RESULT
It should show the correct result of exponentiation, in this case, ~11.09.

Cannot reproduce; maybe a qalculate issue?

It shouldn't be, qalculate runs in it's own thread.

Nothing of the sorts happens when I type the same expressions on `qalc`.

You could try to disable the calculator runner and check if the problem is still reproducible
Comment 5 tmpod 2022-08-02 12:05:02 UTC 
Just tested it again, and it seems to be fixed in KDE Frameworks 5.96.
