package refuses to unlock

[snowcrash+smart]

on a whim, i launched the smart gui.

in it, MozillaThunderbird (1.5.0.7-0.1 at i586) did -- still -- in fact
show as installed & locked, despite repeated unlock attempts via cmd
line.

so, i unlocked in gui.

quitting gui, and checking at cmd line, now i see:

  % smart flag --show lock
  lock
      fwbuilder
      fwbuilder-ipt
      gnucash = 1.8.12-18 at i586

trying,

  % smart remove MozillaThunderbird

seems to have done the trick!

this is the 1st time that something worked @ gui, that did NOT work
for me @ shell.
