I've just updated pyGtranslator. Looks like google online translator changed few things, thats why pyGtranslator wasn't working anymore. It's using a google api now. Hope we will not exceed 100,000 characters/day limit :) 

I've build just 64 deb, because i don't have any 32bit system running any more. pygtranslator_0.6-1_amd64.deb

To be honest, I'm rather using online version, so i don't know if I will continue updating it in the future. But if you find it useful, drop me a line and will fix it, if i can.
