Reopening a ticket on dev.laptop.org

[Mikus Grinbergs]

I reopened a ticket which I believed had been prematurely closed -- 
and somewhere along the line the original description of the problem 
(for which that ticket had been written) got lost.

Can that original description be retrieved from trac ?

What can I do in a future situation to ensure that reopening a 
ticket does not over-write the problem's original description ?

Thanks,  mikus
