[Bug 1458352] [NEW] "Key sequence '...' is ambiguous" message box on almost every shortcut

[DimanNe]

Public bug reported:

Every time I enter "Home", "End", "Shift+Ins" Kate shows me dialog box,
which says

The key sequence 'Home' is ambiguous. Use 'Configure Shortcuts'
from the 'Settings' menu to solve the ambiguity.
No action will be triggered

But when I try to fix it (and I did NOT break it, ie before updating to
Kubuntu 15.04 / KDE 5 all worked well) in Configure Shortcuts, I got
several problems


1) Seems that this shortcut is actually shortcut for the only action (https://img-fotki.yandex.ru/get/15581/11330794.1d/0_bc945_764f522a_orig)
and there is no any ambiguity.


2) When I try to remove "Home" from "Alternate" column and assign it to "Shortcut" column I got cryptic message

The "Home" shortcut is ambiguous with the following shortcut.
Do you want to assign an empty shortcut to this action?
Shortcut '' for action 'Move to Beginning of Line'

3) And finally, I press "Reassign" button get correct shortcuts:

then click "Ok"
and again try to press "Home" in Kate I again get dialog box from 1st point (The key sequence 'Home' is ambiguous. Use...)
