Package: dansguardian
Version: 2.10.1.1-4
Severity: important
Dear Maintainer,
Dansguardian seems not to work on AMD64 systems. I'm sure its not a
dansguardian problem and that some other package has broken DG.
Looking as strace's it looks like a memory problem, but I this exact
same problem on 2 different boxes, both with AMD CPU's
This stuck out when stracing the dansguardian binary:

As a work around you can install the 32 bit version. Download the binary
run alien -t the create the tar extract the binary, and copy to /usr/sbin
Install ia32-libs-gtk.
Download the 32 bit versions of libtommath.so.0 and libclamav.so.6 and
extract them in the same way.
I extracted these and appended .ia32 to the end so they didn't conflict
with the x64 libs, then removed the x64 links and linked to the 32 bit ones.
Any ideas?
Jon
