yum remove scrollkeeper fails

[Gianluca Sforna]

I just tried a:

yum remove scrollkeeper

this pulled in for removal zenity, but then failed like this:

Running Transaction
  Removing  : scrollkeeper                 ######################### [1/2]
  Removing  : zenity                       ######################### [2/2]
/var/tmp/rpm-tmp.9852: line 1: scrollkeeper-update: command not found
error: %postun(zenity-2.16.3-1.fc6.i386) scriptlet failed, exit status 127

because it seems scrollkeeper was removed before the potsun scriptlet
run the scrollkeeper-update command.

is this something for BZ?
if so which component?
