Mostly, the Alpha,Beta,RC series are used by people (like me :P) who want to contribute by sending apport crash reports for the benefit of Ubuntu Linux.
The majority of users wait for/prefer stable releases so they don't even know what is this wonderful "apport" and most likely they don't even have or want a launchpad account... They are just consumers...
This is a problem because they are the majority so too much information for bugs is being lost this way...
What i propose is a deferent approach in apport when we are dealing with stable releases. For this, LaunchPad should collect Anonymous Bug Reports from users that don't want/have an account.
This is a simplified scenario :
--> Totem crashed.... Apport pops up by telling "We are sorry for inconvenience, We are ready to inform this issue to Canonical, would you like to proceed"
--> Then user has 2 buttons "Proceed" and "Cancel"
--> User presses "Proceed", then there is a simple empty box where user is kindly asked: "Please provide as in few words what where you doing before the problem occurred"
--> User can write in few words what was supposed to happen but instead something went wrong.
--> And lastly user presses "send"... and everybody is happy!
All this report is send Anonymously but nevertheless on this hypothetical wizard should have in one way or another an "Advanced" way of reporting where user is proposed to create in few minutes an LaunchPad Account.
