I'm trying to run Defense Zone Lite version 1.5.2-0ubuntu1, but I can't get it to start properly. Running from the terminal, I get this output:

$ /opt/defensezone-lite/Defense\ zone\ Lite
Found path: /opt/defensezone-lite/Defense zone Lite
Mono path[0] = '/opt/defensezone-lite/Defense zone Lite_Data/Managed'

Debug info from gdb:

Could not attach to process.  If your uid matches the uid of the target
process, check the setting of /proc/sys/kernel/yama/ptrace_scope, or try
again as the root user.  For more details, see /etc/sysctl.d/10-ptrace.conf
ptrace: Operation not permitted.
No threads.

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.

How can I fix this?

I think this is just a bug. Did you install it using the Ubuntu apps package available here? If so, report this to the maintainer of the package or the Ubuntu bug tracker. See also How do I report a bug?. –  gertvdijk Dec 28 '12 at 11:42
