I performed a scan yesterday using Nessus 3.0.4 and NessusClient 1.0.0 on an
FC6/i686 machine. Nessus was installed via rpm. I am experiencing a
segmentation fault in the NessusClient binary when attempting to view a
saved scan. This also happens at the end of a scan when NessusClient
attempts to display the scan's results. Here are the last few lines of the
strace:

To be sure that it wasn't something specific to the file, I also tried to
open an older NBE file that was created with Nessus 3.0.3 and one of the RC
versions of NessusClient. NessusClient 1.0.0 segfaulted again in pretty
much the same way.
