Hi!

When I add a service notification with Assign where service.name = NRPE /scratch/backup/volumebackup Usage Check the configuration looks like:

assign where match("hostxy*", host.name) && service.name == "NRPE \/scratch\/backup\/volumebackup Usage Check"

The result is:

critical/config: Error: Bad escape sequence found: \/

                                                                                                                                                                                                   ^^

Best regards,

This bug is caused by writing the assign condition to the database urlencoded when a containing a slash.

Perhaps this helps in fixing it.

Yesterday evening I opened one of the bottles I got from you, that helped with fixing this ;-)
