[leafnode-list] fetchnews-2.0b8_ma8rc1 segfaults after eading "LIST NEWSGROUPS"




With one of my servers (running DNEWS 5.4g5 S0), leafnode 2.0b8_ma8rc1
crashes with a Segfault. -vvvvvDD output and gdb backtrace
is appended.

Another of my servers runs DNEWS 5.4g5 S1, this one works OK.

This is on Linux 2.4.14, RedHat 7.1.
