Description of problem:
After one of the recent clamav updates I see that clamav-milter uses 100% cpu. 
strace shows a tight loop of:

22272 gettimeofday({1122994371, 371311}, NULL) = 0
22272 clock_gettime(CLOCK_REALTIME, {1122994371, 371339000}) = 0
22272 futex(0x805c958, FUTEX_WAKE, 1)   = 0
22272 open("/var/lib/clamav", O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY) = 4
22272 fstat64(4, {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
22272 fcntl64(4, F_SETFD, FD_CLOEXEC)   = 0
22272 getdents64(4, /* 6 entries */, 4096) = 192
22272 stat64("/var/lib/clamav/daily.cvd", {st_mode=S_IFREG|0644, st_size=147768,
...}) =
0
22272 stat64("/var/lib/clamav/main.cvd", {st_mode=S_IFREG|0644, st_size=2337370,
...}) =
0
22272 getdents64(4, /* 0 entries */, 4096) = 0
22272 close(4)                          = 0


Version-Release number of selected component (if applicable):
