Just tested it again, and it seems to be fixed in KDE Frameworks 5.96.

> Cannot reproduce; maybe a qalculate issue?

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

[krunner] [Bug 456339] New: Fractional exponent freezes whole app

[tmpod]

https://bugs.kde.org/show_bug.cgi?id=456339

Bug ID: 456339
   Summary: Fractional exponent freezes whole app
   Product: krunner
   Version: 5.24.5
  Platform: Manjaro
OS: Linux
Status: REPORTED
  Severity: crash
  Priority: NOR
 Component: calculator
  Assignee: alexander.loh...@gmx.de
  Reporter: t...@tmpod.dev
CC: plasma-b...@kde.org
  Target Milestone: ---

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.
