SUMMARY After upgrading kbookmarks to 5.69.0, tmux in Konsole (in most time) crashes Konsole when Ctrl-B (which is a fundamental hotkey of tmux) is pressed at the first time. Rolling back to kbookmarks 5.68.0 solves this. STEPS TO REPRODUCE 1. Install tmux 2. Run tmux in Konsole 3. Press "Ctrl-B C" (create a tab in tmux by default) OBSERVED RESULT First press: tmux has no response to the key, and Konsole crashes. Non-first press (if Konsole didn't crash): tmux has no response to the key. EXPECTED RESULT tmux responses to the key, creating a tab.

I can confirm the bug, but for me it acts slightly different. Gentoo user here, upgraded to kbookmarks-5.69.0 yesterday. For me it doesn't crash. Noticed today that I could not issue Ctrl+B as usual to issue tmux commands in Konsole. Somehow I figured out I had to issue Ctrl+Shift+B in order to have the hotkey functionality. After 1h poking, I discovered in "System Settings > Standard shortcuts" that Ctrl+B was bound to "Add bookmark" action. Removed it, I can finally use tmux properly again. I don't recall ever clearing that hotkey before to have tmux working, I think Ctrl+B was still at its default settings. I also tested by adding a "test" user to my system to check the out-of-the-box configuration, and the bug appeared there as well. It seems to me that the "Add bookmark" action became suddenly available (or bound) to Konsole as well after the upgrade.

As has been said in comment#1 a simple workaround is to change the "Add Bookmark" shortcut in systemsettings -> Shortcuts -> Standard Shortcuts to anything else other than Ctrl+B. Proposed fix https://invent.kde.org/kde/konsole/-/merge_requests/76

[BookmarkMenu] Adapt the code to KBookmarks 5.69 changes Starting from KBookmarks 5.69 the ctor that took a KActionCollection parameter has been deprecated, and we need to manually add the various bookmark actions to the actionCollection so that they show up in the shortcusts editor. Move the code that overrides the add bookmark shortcut, Ctrl+B, to the BookmarkMenu class, so that all the relevant code is in one place.
