Exactly the same mains filter capacitor (or *very* similar) burnt out
in two of my //e power supplies. It seems this is pretty common when
the power supply has not seen any use for a long period of time.

It is fairly easy to find replacement capacitors and do the
replacement. I replaced the failed capacitor in both of my //e power
supplies and both are now working fine.

BTW, doesn't the smoke smell bad?!?  I couldn't get the whiff out of
the house for over a week.  :-)
