You should at least let somebody do something wrong before telling them not to do it!!
Based on this, One would also let someone walk into a busy street, without even looking both ways, or waiting for the cross walk light to turn green.
I think it is better to tell some one before they make the mistake, when it is pretty clear
they are about to do something they shouldn't.
Would you also let 2 children play with a loaded gun, instead of telling them not to do that, ? You would just go ahead and let them play, so they learn some lesson after one of them pulls the trigger and gets shot.
Or somebody asks about using Ubuntu repos in their sources,list file,...are you saying
we should just go ahead and say , yes do it ,...then after they have wrecked there system
tell them, they shouldn't have done that.
When some one does not know if something is right or wrong, it is important to tell people before they do something wrong, so they know it is wrong.
The OP did do the right thing by asking here first.
Not knowing for sure, if the problem or bug was related to the recent posts, but also knowing the OP can easily misunderstand, telling them , Yes start another to topic about this bug, probably would result in another post about the same problem, and I wanted to try to help them avoid getting more people upset,...
But in any event, I apologize for making a assumption, or if anything I said seems rude.
If the links I posted are not enough, and the OP still does not understand how to file a bug report, of course they are welcome to start a topic on that, and see if anyone can help them.
