Bug 463283

SUMMARY
***
I am trying to archive emails via keyboard shortcut and somehow the assigned key works only once. 
***

STEPS TO REPRODUCE
0. Set up A folder for Archiving via Settings/Configure Kmail/Accounts/Receiving/Archive Folder
1. Open Settings/Configure Keyboard Shortcuts 
2. Filter/Search by "archive"
3. There are two options, "Archive" and "Archive Folder"
4. Select "Archive"
5. Set custom shortcut, I tried several and none worked, but for this example let's use Alt-A
6. Press Ok to save
7. Repeat 1-3 to confirm the setting is still there
8. Navigate to the folder set up for Archiving
9. Hit Alt-A
10. Email under cursor disappears and is moved to Archive location, as expected
11. Hit Alt-A a second time, nothing happens
12. Repeat 1-3 to observe that the shortcut has disappeared

I am able to repeat this as often as I want, the shortcut gets deleted after first usage.
I also tried the "Archive Folder" option in step 3, in this case the shortcut is not deleted, behaves as expected.

EXPECTED RESULT
Shortcut is not deleted after first use.

I have seen this one here: https://bugs.kde.org/show_bug.cgi?id=345992 but wasn't sure if it's ok to bring this 4 year old zombie back to live or if I better start a new.
