Thunar does not recognices mimetype asociation in PDF and OpenDocument

[jEsuSdA 8)]

Hi!

I have a problem I can not solve instead I have spend a lot of time 
trying to solve. :(

When I click a pdf file in Thunar, this pdf opens with ePdfViewer 
instead Evince.

Evince is the software designed for opening pdf files in Thunar and in 
the XFCE mimetype editor. [screenshot 2 and 3]

This has been working ok since ever, but suddently it stop working and 
Thunar opens pdf files with the wrong applicacion.

This happens too with LibreOffice files (odt, ods, etc.). Thunar opens 
this files with Calligra instead LibreOffice.

The others mimetypes associations works fine. Only PDF and LibreOffice 
files opens wrong.

How I can see what is happening? How I can solve this problem?

Thank you.
