[khelpcenter] [Bug 461468] Crash when pressing particular sequence of function keys
https://bugs.kde.org/show_bug.cgi?id=461468 --- Comment #3 from Jack --- Settings/Configure Keyboard Shortcuts says F7 is "Toggle caret mode." I can't find any mention about khelpcenter having caret mode. Even searching the source files, the only mention I see of F7 is for Ctl-F7 "Present Windows of current application only" in the section on "Moving Around." I wonder if the system is getting confused because that key combination (just F7) doesn't actually map to anything in khelpcenter. -- You are receiving this mail because: You are the assignee for the bug.

I get the same crash just typing F7 twice.
