why are source packages sometimes yum inaccessible?

[Robert P. J. Day]

  i've had this issue before but, every so often, i just can't grab a
src.rpm for a given package:

$ yumdownloader --source file
Loading "refresh-updatesd" plugin
development               100% |=========================| 2.1 kB    00:00
primary.sqlite.bz2        100% |=========================| 5.2 MB    00:08
kde-all                   100% |=========================|  951 B    00:00
kde                       100% |=========================| 1.1 kB    00:00
development-source        100% |=========================| 1.9 kB    00:00
Enabling development-source repository
No source RPM found for file - 4.21-3.fc8.i386
Nothing to download
$

  is there a reason for this?
