Comment 20 for bug 51419

Just to clarify what appened to other people: we, the Italian Ubuntu translators, have used the following translation for a message in update-manager:

   Attendere, l'operazione potrebbe richiedere del tempo

Unfortunately this message is passed via command line to synaptic, adding the ' (apostrophe) too. (see bug 67112 for details)

This should be the cause of the misbehaving.

Wating for the upstream fix, the message was changed, removing the ' (s/l'operazione/questo), so the next langpack update should also fix the misbehavior. I'll report on it.

I beg your pardon!
