When clicking on 'Select All' button on channel package listing page, instead of selecting all the packages available in the given channel, some random packages are selected instead. For example, in Red Hat Enterprise Linux (v. 5 for 64-bit x86_64) channel, which right now holds 9,349 packages, clicking that button yields 945 selected packages. An additional twist is the packages selected in that way cannot be found in the package listing page, it seems they have been erroneously taken from some other channel.
