yeah, it's a bug in 1.1 which is fixed in the debian patched 1.0.4-4. If you
built from source here's the workaround:


diff -u -r1.4 -r1.4.2.1
--- lv_check_consistency.c      7 Feb 2002 16:19:46 -0000       1.4

    if ( lv == NULL)                                   ret = -LVM_EPARAM;
    else if ( lv_check_name ( lv->lv_name) != 0)       ret = -LVM_ELV_LVNAME;
    else if ( vg_check_name ( lv->vg_name) != 0)       ret = -LVM_ELV_VGNAME;
