e2fsck segmentation fault

[Petr Janda]

Hi,
Im trying to run e2fsck on a mounted ext2 filesystem image, with this 
result:

elevator# e2fsck -f /dev/vn0c
e2fsck 1.32 (09-Nov-2002)
The filesystem size (according to the superblock) is 262144 blocks
The physical size of the device is 0 blocks
Either the superblock or the partition table is likely to be corrupt!
Abort<y>? no
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information
/dev/vn0c: 11057/131072 files (0.1% non-contiguous), 58256/262144 blocks
Segmentation fault
Im doing this because I want to resize the filesystem.  Can anyone have 
a look into this please?
