Subject: Bug#265069: bogofilter: segfaults when using ignore list option

Package: bogofilter
Version: 0.92.4-1
Severity: normal

When trying to tune my filtering mechanism I wanted to make use of the
ignore list wordlist option. However, bogofilter stopped working then
and some research revealed that just using that option cases a
segfault.

how to repeat:
# (copy'n'paste friendly edition :)
mkdir /tmp/.bogofilter
# initialize wordlist.db using an arbitrary message
bogofilter -s -d /tmp/.bogofilter/ <bogo-test.msg                             
# initialize ignore.db
echo foo | bogoutil -l /tmp/.bogofilter/ignore.db

# now do anything, e.g. config check
bogofilter -d /tmp/.bogofilter/ '--wordlist=I,ignore,ignore.db,2' -Q
# Segmentation fault

# or check that message
bogofilter -d /tmp/.bogofilter/ '--wordlist=I,ignore,ignore.db,2' <bogo-test.msg
# ditto

# the problem is appearently within the processing (opening?) of type
# I(gnore) worldlist since treating that list as R(egular)
bogofilter -d /tmp/.bogofilter/ '--wordlist=R,ignore,ignore.db,2' -Q
#                                           ^
# works

last words (from strace):

fcntl64(3, F_SETFD, FD_CLOEXEC)         = 0
