Bug ID: 461468
Summary: Crash while pressing random function keys
Classification: Applications
Product: khelpcenter
Version: unspecified
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kde-doc-english@kde.org
Reporter: gerbils...@gerbilsoft.com
Target Milestone: ---
While cleaning my keyboard, I managed to somehow crash KHelpCenter (22.08.3;
this version isn't in the list).
I've narrowed it down to the following steps:
* Open KHelpCenter (e.g. by pressing F1 in KWrite).
* Press the following keys in sequence: F3, F1, F7
* Repeat the sequence: F3, F1, F7
Application: Help Center (khelpcenter), signal: Segmentation fault
