[Pkg-dspam-misc] Bug#726138: dspam css file size dramatically increased after upgrade

[Sylvain LEVEQUE]

Package: dspam
Version: 3.10.2+dfsg-10
Severity: important

Dear Maintainer,

After upgrading from 3.10.2+dfsg-9 to 3.10.2+dfsg-10, the size of the css file located in /var/spool/dspam/data/local/$USER/$USER.css increased from around 4.5MB to 2.6GB.
It couldn't grow any longer, as it had filled the disk of the VPS, which in turn broke lots of services on this system.

After stopping dspam, deleting the large css file and rebooting, a new css file was created, which is now of 1.6GB, leaving some spare disk on the VPS.

The upgrade log:
# grep dspam /var/log/dpkg.log | grep upgrade
2013-10-11 15:08:18 upgrade dspam:amd64 3.10.2+dfsg-9 3.10.2+dfsg-10
2013-10-11 15:08:18 upgrade libdspam7-drv-hash:amd64 3.10.2+dfsg-9 3.10.2+dfsg-10
2013-10-11 15:08:18 upgrade libdspam7:amd64 3.10.2+dfsg-9 3.10.2+dfsg-10
2013-10-11 15:08:44 upgrade dspam-webfrontend:all 3.10.2+dfsg-9 3.10.2+dfsg-10

Please find attached the evolution of the disk space over time that highlights the issue upon upgrading.

I am the only user on this machine, so I don't know if the same issue would affect other css files or not. I have backups of the files before and after upgrade if more information is required.

Thank you

Sylvain
