Hobbit client logfetch core dumps on 4.2.0 with all the patches

["Sebastian" <spa (at) syntec.co.uk>]

Hello,

I have one hobbit client that produces a core dump every 5 minutes when
logfetch is run.  It is running the same version of Hobbit client (4.2.0
with all the patches, which I believe has the same logfetch.c as the latest
snapshot) as another machine and both have the same OS (including same
version of glibc) and the same client-local.cfg configuration on the Hobbit
server.  However, only one of these machines core dumps.  Here is the back
trace:

[root (at) myServer hobbit]# gdb /usr/libexec/hobbit/client/bin/logfetch

The client-local.cfg is this:
[myServer]
log:/var/log/messages:10240
ignore session\s(?:closed|opened)\sfor\suser\sroot
log:/var/log/maillog:10240
dir:/var/spool/mqueue

Eventually, of course, the partition fills up with all the core dumps!

Kind regards,

Sebastian
