The issue has been fixed sometime in the past.

Current spacewalk nightly works properly:

Package spacewalk-backend-1.9.28-1.

VERIFIED on spacewalk-backend-2.0.3-18.el6sat (Sat5.6.0-RHEL6-re20130917.0)
REPRODUCED on spacewalk-backend-1.2.13-11.el5sat (Sat 5.4.0)

Steps to reproduce:
1. Download some packages, create rep and create repositories in sattelite.
This reproducer is for Sat5.6.0 (Sat5.4.0 has not channel.software.createRepo, channel.software.disassociateRepo, channel.software.associateRepo). We have to do steps (where are unsupported APIs) using WebUI.
> mkdir /var/www/html/pub/fuse
> cd /var/www/html/pub/fuse
> wget http://download1.rpmfusion.org/free/fedora/releases/19/Everything/i386/os/kmod-xtables-addons-2.3-3.fc19.i686.rpm http://download1.rpmfusion.org/free/fedora/releases/19/Everything/i386/os/kmod-xtables-addons-3.9.5-301.fc19.i686-2.3-3.fc19.i686.rpm

> rm kmod-xtables-addons-2.3-3.fc19.i686.rpm
> export PASSWD="xxx"
> spacewalk-api --server localhost --user=admin --password=$PASSWD channel.software.createRepo "%session%" "my-url-repo" "YUM" "http://localhost/pub/fuse"
> spacewalk-api --server localhost --user=admin --password=$PASSWD channel.software.createRepo "%session%" "my-file-repo" "YUM" "file:///var/www/html/pub/fuse/"
2. Create custom channel
>python
>>> import xmlrpclib;
>>> client = xmlrpclib.Server('http://localhost/rpc/api', verbose=0);
>>> key = client.auth.login('admin','xxx');
>>> client.channel.software.create(key,"my-channel","my-channel","my-channel","channel-ia32","",{});
3. associate the "my-file-repo" repo and do repo-sync
> spacewalk-api --server localhost --user=admin --password=$PASSWD channel.software.associateRepo "%session%" "my-channel" "my-file-repo" 
> spacewalk-repo-sync --channel "my-channel" --type yum

4. change the repo and again repo-sync

> spacewalk-api --server localhost --user=admin --password=$PASSWD channel.software.associateRepo "%session%" "my-channel" "my-url-repo"
