Bug#434598: op-panel: Cannot be uninstalled

[Jim Thomas]

The problem is with the 
  update-alternatives --remove-all op-panel
line in /var/lib/dpkg/info/op-panel.prerm

"set -x" added to /var/lib/dpkg/info/op-panel.prerm:

  # aptitude remove op-panel
  [snip]
  The following packages will be REMOVED:
    op-panel 
  0 packages upgraded, 0 newly installed, 1 to remove and 0 not upgraded.
  Need to get 0B of archives. After unpacking 1143kB will be freed.
  Writing extended state information... Done
  (Reading database ... 236843 files and directories currently
  installed.)
  Removing op-panel ...
  + case "$1" in
  + update-alternatives --remove-all op-panel
  No alternatives for op-panel.
  dpkg: error processing op-panel (--remove):
   subprocess pre-removal script returned error exit status 1

Commenting out "update-alternatives --remove-all op-panel" allowed
package removal.

Installing and subsequently removing op-panel is now ok.

Possibly that line needs modification.
