Please describe the problem:
I create a new header for checking junk.But I can not see the new added header in the for junk header list.

Steps to reproduce:
1. Launch evolution,select "Edit"->"Preferences"->"Mail Preferences"
2. Select "Junk" tab,check the "Check custom header for junk".
3. Click "Add" to add a new header name.


Actual results:
I can not see the new added header in the junk header list.

Expected results:
I can see the new added header in the junk header list.

Does this happen every time?
yes

Other information:
You can retry steps for many times,then you will see the last added header.But the new added header is still disappear.

Or you can select one header in the list to delete.Then you will find the selected header still in the list.
