Hmm, indeed, looks like I got carried out there, sorry about that. And yeah, 
I agree with that there should be a way to give a clear message to the

Keeping up the information in two separate databases wouldn't do good was my 
ppint. But yeah, perhaps b.k.o should have some kind of separate field for 
that kind of information, which would be then given out as needed.

Yeah, agreed. In my opinion the comment section of bug entries could be even 
more cleaned out, to just contain comments for example. Tens of "marked as 
duplicate of" messages do not bring much more info while disturbing the real 
comments. Mozilla uses an extension called inline history which shows 
changes to bug statuses and also combine successive duplicate reports, 
though the process is apparently so heavy the feature is not enabled for 
users not logged in.

Hmm, yup. The traceparser makes inlined backtraces to be not so verbose, but 
doesn't remove the problem completely.

True, perhaps a separate field could be provided, and the comment closing 
the bug could be used if none specified?

Yup, this comment was more about not having a need to create a separate 
login, as I think that'll still be the barrier for getting reports. But 
yeah, there are two sides in this.

Well, basically if the reporting crashes will be much easier (esp. if no 
login is needed) and there'll be loads of more reports, then issues might 
surface on this front. This was mostly food for thought though.

Well, from what I've seen in bko people do ask whether the bug is still 
reproducable, no? I see no reason why this information should pollute the 
comments section, which should be in my opinion used for discussing the 
specifics of the bug.

False positives, if that can happen. Also, this kind of information could be 
used as a base to see from what kind of things bugs are triggered mostly? 
But yeah, just thinking...

Indeed. Sounds good to me.
