configure thunar default actions

[Kai-Martin Knaak]

Hi,

I'd like to customize the default application for a certain type of files. 
This is what I did:

1) right-click on one of the files

2) Open_With -> Open_with_other_Application

3) check Use_as_default_for_this_kind_of_file

4) select one of the recommended application

5) left-click on "Open"
  as expected, the file is opened with the selected application 

Now, right-click -> Properties shows the newly configured application. 
In addition, xdg-open, gvs-open and exo-open all use the newly configured 
application. 

In spite of this, the menu I get with right-click on the file still shows 
the old default application in the top line "Open With...". 
Consequently, a double-click insists to use the old default. 

A restart of thunar after killing it with "thunar -q" had no effect. File 
properties show my desired default application but double click stubbornly 
opens with the old. Same with a complete session logout-login. 

Am I missing something obvious?
Any checkbox I should check?
Does anyone else see this behavior?

Is there a config file for thunar where this kind of information is 
stored?

PS: My system is debian/testing, updated weekly. 
    Thunar is at version 1.6.3.1-1
