My way to get this stacktrace:
dspam:/etc/dspam$ ls -l
total 88
-rw-r--r--  1 root  root     31 2010-08-12 17:52 admins

dspam:/etc/dspam$ sudo -u www-data dspam_stats
Unable to read dspam.conf

OKAY!!

dspam:/etc/dspam$ sudo chgrp www-data dspam.conf dspam.conf
dspam:/etc/dspam$ sudo -u www-data dspam_stats
*** glibc detected *** dspam_stats: double free or corruption (!prev): 
0x0804e768 ***

:(((

id www-data
uid=33(www-data) gid=33(www-data) groups=33(www-data)

www-data can go into dspam.d
www-d...@dspam:/etc/dspam$ cd dspam.d/
www-d...@dspam:/etc/dspam/dspam.d$

but can not read any file

www-d...@dspam:/etc/dspam/dspam.d$ ls -l

-rw-r----- 1 dspam dspam 2475 2010-08-10 08:00 extlookup.conf

-rw-r----- 1 dspam dspam 2225 2008-02-24 21:17 mysql.conf

www-d...@dspam:/etc/dspam/dspam.d$ cat extlookup.conf
cat: extlookup.conf: Permission denied

same stacktrace without sudo - use sudo only for "faster" user switching :)
