The backtrace at the segfault is this:

#0  0x080748b9 in addslashes (in=0x0) at addslashes.c:15
#1  0x0804d62c in _cli_dump_plugins (plugins=0x84b5a70) at cli.c:602
#2  0x0804d96e in cli_dump_plugins (cli=0x80d9900) at cli.c:673
#3  0x0806d55d in main (argc=8, argv=0xbffff8a4) at nessus.c:1130

cli_dump_plugins calls _cli_dump_plugins(Context->plugins).
Context->plugins is a pointer to struct nessus_plugin.
_cli_dump_plugins expects a struct arglist pointer though. 
Chaos ensues.

It seems this is a leftover from the change from arglist to
nessus_plugin structs for the plugins in nessus client.
