Description of problem:
I have a file containing ext2 filesystem (created just by mke2fs -F file).
When I've accidentally gave resize2f an bogus size argument, the command went on crazy loop instead of some graceful 'learn to type, user' refusal.

# resize2fs /tmp/tmp.lntZtMFvz8/fake-disk bogus 2> log
Resizing the filesystem on /tmp/tmp.lntZtMFvz8/fake-disk to 0 (1k) blocks.
...waiting for 10 seconds... ok, thats enough
^C
[root@dhcp-lab-123 smoke-test]# cat log | wc -l
627587
[root@dhcp-lab-123 smoke-test]# head log
resize2fs 1.41.0 (10-Jul-2008)
Illegal block number passed to ext2fs_test_block_bitmap #1 for block bitmap for /tmp/tmp.lntZtMFvz8/fake-disk
...the same message repeated zillion times...

Version-Release number of selected component (if applicable):
resize2fs 1.41.0 (10-Jul-2008)
[root@dhcp-lab-123 smoke-test]# rpm -q e2fsprogs
e2fsprogs-1.41.0-2.fc9.x86_64

How reproducible:
always for me

Steps to Reproduce:
1. dd if=/dev/zero of=gggg bs=1024k count=42
2. mke2fs -F gggg
3. resize2fs  gggg bogus 

Actual results:
loop 

Expected results:
graceful end and some user insult

Additional info:
I've tried that on RHEL5.2 e2fsprogs. resize2fs handles this case gracefully there:
# resize2fs /tmp/disk rd
resize2fs 1.39 (29-May-2006)
resize2fs: bad filesystem size - rd
