Hi Rodrigo,
Sorry, command-not-found has crashed! Please file a bug report at: https://bugs.launchpad.net/command-not-found/+filebug Please include the following information with the report:
It means that command-not-found, a script that is triggered when you mistype a command in the shell, has failed. That's what the message states pretty clearly, and it also states as clearly that the place to report this is not the OpenLDAP mailing list ;).
Cheers, Nik
