when closing x2goclient there is the message
  x2go-INFO-6> "X2GoClient wird geschossen ..."
which should read 
  x2go-INFO-6> "X2GoClient wird geschlossen ..."
instead. It is the translation of
  Closing X2Go Client ...
which is on line 1938 in file res_i18n_x2goclient_de.ts
  code.x2go.org/gitweb?p=x2goclient.git;a=blob_plain;f=res/i18n/x2goclient_de.ts;hb=HEAD
