After going to Settings > Configure Shortcuts and changing "Alternate" shortcut for "Paste" action and closing/reopening konsole, shortuct is reset to bad value.
Main Shortcut is set to blank and alternate one is reset to Ctrl+Insert.
Steps to Reproduce:
1. open konsole and go to Settings > Configure Shortcuts
2. set "Alternate" shortcut for "Paste" to whatever combination
3. press OK
4. close konsole
5. reopen konsole
Defined shortcut doesn't work and is reset to strange values.
Defined shortcut should work.
Am using KDE Frameworks 5.6.0, Plasma Desktop 5.2.0 on Arch Linux.
Issue was happening with konsole 14.12.1 (on plasma5, it was working fine in kde4 desktop), and is still happening after upgrade to konsole git version 3.90.901 394d1e8
I can confirm the behavior, also using Archlinux, KDE Frameworks 5.6.0 and plasma 5.2, kde apps 14.12.1.
It seems that, setting any alternative shortcut resets both primary and alternative shortcut after konsole is closed.
1. Set alternative shortcut for next tab (Ctrl+Tab).
2. Both primary (Shift+right) and alternative (Ctrl+Tab) shortcuts work.
3. Close all konsole windows.
4. After starting konsole again, both shortcuts for switching to next tab are erased.
Have checked out a code and this seems to be a bug in kxmlgui.
After customizing shortcut with KShortcutsDialog it appends default shortcuts to QList<QKeySequence> so it ends up being a pretty long list of duplicate shortcuts like this:
Pri+Shortcut+You+Just+Set; Alt+Shortcut+You+Just+Set; Previous+Primary+Shortcut; Previous+Alt+Shortcut
And it grows by two every time you edit the list.
Have created a patch here: https://github.com/maxrd2/kxmlgui/commit/966f6ad78a4831f49e1bfb759315b7499346b9d5
I've altered the code in few places to remove everything behind Primary and Alt shortcut.
It's probably a crappy solution, but it fixes the issue for the moment.
Hope it will help someone before a real patch is submitted.
Also paste shortcut cannot be changed in konsole and it's not caused by this.
If you try to change 'edit_paste' shortcut on next load it gets changed to " ; Ctrl+Ins".
It loses primary shortcut and alt one gets reset.
