Thank you Oliver for great help with this wiki page. I would suggest adding also a way to create *.mo files to test them live on our systems.

Regarding affected files there are probably others too:
You updated file libDrakX-standalone.pot on 18 or 19 January.
I had string mix up in libDrakX.pot_sl.po.
Rémi mentioned string mix up in drakx-net.

Have fun,
Filip.
