Comment 2 for bug 354634

That means that possibly sensitive information will be publicly available because reporters often won't see that the bug privacy status got changed to public automaticly or even more often they don't have the skills to know what needs to be private... (and in case it's a common crasher bug, no developer is going to set 100 bugs back to private manually instead of fixing the bug).

I still think duplicate bugs should have the same private/public status as the main bug, just to be safe...
