Thank you for this suggestion, unfortunately it didn't change anything. 
The function os.getenv('LANG') returns 'cs' for my system. So I do 
believe the localization file should be placed in 
locale\cs\LC_MESSAGES\translate.mo. But it doesn't work neither. Do you 
have any other idea what could be wrong?

A working sample application would be a huge help for me.

Thank you for your time and support.
