That's excellent detective work on your part tracking down the cause.

I think the file
~/.local/share/kxmlgui5/kmail2/kmmainwin.rc
is created/updated if you configure the toolbar. The bug may be that it's not 
updated if a shortcut is added to a filter.

The above mentioned note is for developers who change the kmmainwin.rc in the 
source code to also change the kmail_part.rc (and vice-versa). There is no 
automatic synchronization between user-specific .rc files (and it could be 
undesired because users might want to have different toolbar entries in KMail 
and Kontact).

Yes, could be. I guess shortcuts that are explicitly defined in the filter 
configuration should take precedence over the information in the .rc files.

Ingo
