Partition full after deleting a large file

[Marcus Better <marcus@better.se>]

Hi,

a buggy mail client (kmail) filled up my 4 Gb /home partition by filling
the .xsession-errors with several gigabytes of the same error message. I
removed the file, which was well over 2 Gb. But "df" still shows zero free
space, and I cannot create new files.

The /home partition is on a dmcrypt volume on LVM. The system is a Thinkpad
R60 (Core 2 Duo) running Debian unstable with custom kernel 2.6.20-rc6
(from the wireless-dev tree).

Here is some debug info:
~# df /home/
