I found the setting that triggers this bug. In the current Konsole profile settings, go to the Advanced page and set Ctrl as the key combination to show URL hints.

Can confirm this issue. URL hints in general have stopped working for me. Using konsole built from git -master.

Seems reverting commit 1c0b4e81e42ca2141f5929cbae6beb9a46c8d465 fixes the issue for me.

Er, nevermind, investigating further.

Okay it might be actually c8b94b8780019dca7511efe1cf110f1b19bf7a7d

I wish bugzilla had edit button :)

Anyway, yes, reverting c8b94b8780019dca7511efe1cf110f1b19bf7a7d fixed the issue for me. Can you also give this a try?

This is the merge request of the crashing commit https://invent.kde.org/utilities/konsole/-/merge_requests/977

In case this is helpful, the following steps always trigger the crash for me:

* Open Konsole

* type in the name of a directory that exists in your working dir
* 
hit Shift+Ctrl once
* 
hit Shift+Ctrl twice

-> Konsole crashes.

ADDITIONAL INFORMATION
Konsole build from master on 2024-04-07.
Plasma also build from master the same day.
Distro: Kubuntu 23.10

There seems to be some weird off-by-one error somewhere. If you resize konsole so that the path goes to two or more lines, hover appears for it, however pressing highlight key still crashes the app.

Without MR (https://invent.kde.org/utilities/konsole/-/merge_requests/977): 

Start and end column show correctly.

With MR:

Start and end column are both 0.

Seems the bug was just misplaced parenthesis https://invent.kde.org/utilities/konsole/-/merge_requests/984

A possibly relevant merge request was started @ https://invent.kde.org/utilities/konsole/-/merge_requests/985

Character: Return stringWidth, not value of ignoreWcWidth

There is a typo with parentheses being in wrong place, so the code returns the value of ignoreWcWidth, not value of stringWidth.
