John,

For Karmic, (very soon, actually), I'm planning on moving this data
from $HOME/.Private to /home/.ecryptfs/$USER/.Private.

How does that affect your work?

Bug description:
Binary package hint: ecryptfs-utils

klamav 0.46-2 with clamav 0.95.
Jaunty with encrypted home directory.

After installing klamav and first running it, it creates /home/user/.klamav/database, in which it downloads the signature databases. This directory gets created OK, but the database download fails with 'Can't create file' error, and the following entry in syslog:

Apr 11 01:11:39 utest-jj kernel: [  959.044919] type=1503 audit(1239401499.961:33): operation="inode_create" requested_mask="a::" denied_mask="a::" fsuid=1000 name="/home/gimre/.Private/ECRYPTFS_FNEK_ENCRYPTED.FWYWbBX-HCv7D-ShpT0P1qAlMITxm.e31aS9aW.rw0ebxHiizvzjKdHqek--/ECRYPTFS_FNEK_ENCRYPTED.FWYWbBX-HCv7D-ShpT0P1qAlMITxm.e31aS9FGYc1fWwp9RQW-wdr8CQZU--/ECRYPTFS_FNEK_ENCRYPTED.FYYWbBX-HCv7D-ShpT0P1qAlMITxm.e31aS9Pcj74.T8NOQNJ4OdUE2-.LWX5l6N.v2lDmBFyCvWlKqrrt-xoaiQuTGvsGqXcTCI" pid=5164 profile="/usr/bin/freshclam"

Apr 11 01:11:39 utest-jj kernel: [  959.045149] ecryptfs_create: Failed to create file inlower filesystem

After stopping apparmor, the problem goes away, the database gets downloaded correctly.

Can be reproduced by correcting freshclam's apparmor profile, see the following bug:
