Another up2date problem

[Thomas Cameron <thomas cameron camerontech com>]

I re-ran up2date -u and this time it appears to have completed, except I
got this error:

/var/tmp/rpm-tmp.21876: line 2: gdk-pixbuf-query-loaders: command not
found

I am not sure which RPM was doing what, though.  There were 506 packages
installed by up2date.

I've Googled some other people who have had this error and they ignored
it.  I am not comfortable doing so.  Anyone know what this means?
