    http://www.capphire.org/collectd/collectd.core.tgz, is a tar-gziped file
with the collectd.conf file, MyPlugin.pm (is the plugin example), the core
file and the collectd.out (with enable debug and logfile plugin with debug
config).

    I try to debug it and this is the gdb backtrace

  I compile it on 2 machines, the first is a Suse 8.2 professional edition
(perl 5.8.0, kernel 2.4.20) and the second a Suse Enterprises 9.3 SP3 (perl
5.8.3 and kernel 2.6.5).
