Everything looks as expected here with Liberation fonts installed. 

Can you install the fonts-liberation package?

Thanks in advance for your answer.

Ok. Can you look at what is shown on font substitution on the "File -> Properties... -> Fonts" tab (what is substituted for the Times fonts)?

Thanks in advance for your answer.

Also, can you please try to remove the gyre fonts from the system?
