lvcreate error

i have created a bunch of logical volumes on a single system with the following commands:
#lvcreate -C n -l 512 -n backuplv -p rw --persistent y --major 253 --minor 255 -r 0 vg0
#lvcreate -C n -l 512 -n datalv -p rw --persistent y --major 253 --minor 254 -r 0 vg0
#lvcreate -C n -l 512 -n homelv -p rw --persistent y --major 253 --minor 253 -r 0 vg0
#lvcreate -C n -l 256 -n optlv -p rw --persistent y --major 253 --minor 252 -r 0 vg0
#lvcreate -C n -l 64 -n rootlv -p rw --persistent y --major 253 --minor 251 -r 0 vg0
#lvcreate -C n -l 128 -n swaplv -p rw --persistent y --major 253 --minor 250 -r 0 vg0
#lvcreate -C n -l 50 -n testllv1 -p rw --persistent y --major 253 --minor 249 -r 0 vg0
#lvcreate -C n -l 50 -n testllv2 -p rw --persistent y --major 253 --minor 248 -r 0 vg0
#lvcreate -C n -l 50 -n testllv3 -p rw --persistent y --major 253 --minor 247 -r 0 vg0
#lvcreate -C n -l 50 -n testllv4 -p rw --persistent y --major 253 --minor 246 -r 0 vg0
#lvcreate -C n -l 50 -n testllv5 -p rw --persistent y --major 253 --minor 245 -r 0 vg0
#lvcreate -C n -l 50 -n testllv6 -p rw --persistent y --major 253 --minor 244 -r 0 vg0
#lvcreate -C n -l 768 -n tmplv -p rw --persistent y --major 253 --minor 243 -r 0 vg0

when i try to create the next one it fails with the following error:
#lvcreate -C n -l 640 -n usrlv -p rw --persistent y --major 253 --minor 242 -r 0 vg0
Physical extent 0 of /dev/hdb2 referenced by more thatn one logical volume. Couldn't fill extent allocation bitmaps vg0.

what did i do wrong?

Please report what version of LVM2 you're using ('lvm version') and what architecture and what kernel.

If it's version 2.00.17 or later, please tar/zip /etc/lvm directory and email it to me (not the list). (Before that version, I'm not interested.) Also enable debugging-to-log-file for the command that fails and send me the complete output (compressed).
e.g. lvm.conf: in log section:

    file="/tmp/lvm2.log"
    level=7

Also (of course) try to reproduce with latest release (2.00.25).
