I came across this report this morning: https://bugs.launchpad.net/ubuntu/+bug/267675.
I set it to Incomplete and asked the reporter to provide more information, on the off-chance that they might actually be trying to report a bug. However, a short while later the same user reported this bug: https://bugs.launchpad.net/ubuntu/+bug/267698.
It seems to me that the user is just messing around.
I'm not sure whether there is a procedure for making the Launchpad admins aware of this.
