I am trying to create a filter where action is to add sender to my address book. So I want to add the "from" field. When I close the filter window and goes back to it, the field where I choose what to add to the address book is cleared.

But this behaviour only appears (at least) when application is in french. When I switch to english it works great.

Reproducible: Always

Steps to Reproduce:
Try to create such a filter when KMail in french. Doesn't work. Switch to English. It works

Actual Results:  
In french, the filed from ("De") and to (À) aren't recorded when saving the filter

Expected Results:  
The filter saves this part of the filter configuration
