Description of problem:  In the xsane-gimp update pushed to FC5 updates today,
there's an error in the postinstall scriptlet:

# yum upgrade
...
  Updating  : autofs                       ####################### [ 4/20]
  Updating  : xsane-gimp                   ####################### [ 5/20]
/var/tmp/rpm-tmp.27650: line 1: [: missing `]'
  Updating  : mutt                         ####################### [ 6/20]
...


Version-Release number of selected component (if applicable):
xsane-gimp-0.991-3.fc5

How reproducible:
Didn't try.

Steps to Reproduce:
1. Upgrade to xsane-gimp-0.991-3.fc5 using yum
  
Actual results: error message (and perhaps something broken)

Expected results: no error message

Additional info:

The following:

$ rpm -q --scripts xsane-gimp
postinstall scriptlet (using /bin/sh):
if [ -x "/usr/sbin/gimp-plugin-mgr"]; then
    /usr/sbin/gimp-plugin-mgr --install xsane
fi
...

shows that there's a missing space between the " and the ].


It seems like this could be the result of the fix for bug 209648 based on
reading that bug (although I didn't look in CVS).
