spamc not working from procmail in Fedora 9

[Daniel Fazekas]

SELinux appears to stop spamc from being called from procmail:
type=1401 audit(1210924808.115:14): security_compute_sid:  invalid  
context system_u:system_r:spamc_t:s0 for  
scontext=system_u:system_r:procmail_t:s0  
tcontext=system_u:object_r:spamc_exec_t:s0 tclass=process

procmail logs:
/usr/bin/spamc: /usr/bin/spamc: cannot execute binary file
procmail: Error while writing to "/usr/bin/spamc"
procmail: Rescue of unfiltered data succeeded

In my .procmailrc I have this line:
INCLUDERC=/etc/mail/spamassassin/spamassassin-spamc.rc

Used to work fine in previous releases of Fedora.
Is there anything I could set to allow this?

I have already tried a full touch ./autorelabel && reboot, it didn't  
help.

SELinux is using
selinux-policy-targeted-3.3.1-42.fc9.noarch
selinux-policy-3.3.1-42.fc9.noarch
