I get the following when yum updating to today's rawhide: libgnomeui 100 % done /sbin/ldconfig: File /usr/lib/libpanel-applet-2.so.0.0.17.#prelink#.twbPRD is too small, not checked.
That's a temporary file left over from prelink, it's not a libgnomeui bug. If you remove it and re-run prelink, does it come back?
Also, did any error related to libpanel-applet-2.so.0.0.17 show up in /var/log/prelink.log?
It appears to have been a transient thing. Re-prelinking doesn't do it again, and there are no errors in the log file....
Then it is very unlikely something can be done about it. There are two possible reasons why the temporary file could stay: 1) prelink process was killed or the system was rebooted during the cron job 2) prelink segfaulted while prelinking the library (in this case it would likely be reproducible though)
