Comment 66 for bug 133567

After standard upgrade from feisty to gutsy (32-bit) I noticed the same problem. First usage of "nautilus" or "df" lasts a several seconds - the problem is only with vfat partitions (I have two pata discs):
/dev/sdb1 on /media/kontener2 type vfat (rw,utf8,umask=007,gid=46) []
/dev/sda6 on /media/kontener1 type vfat (rw,utf8,umask=007,gid=46) []

sequence: "umount /dev/sda6; mount -a; time df" gives ca. real 6.3s, user 0.0s, sys 3.3s.
sequence: "umount /dev/sdb1; mount -a; time df" gives real 1.85s, user 0.0s, sys 1.05s
(in both cases: next "time df" give times under 0.01s)

df:
(...)
/dev/sda6 124828304 73965376 50862928 60% /media/kontener1
/dev/sdb1 39058992 35982816 3076176 93% /media/kontener2

=> time is proportional to size of partition.
