Error using tsung view after running load test

[sgtang]

EDIT: To clarify, this is on v1.7.0

Hi, I was able to successfully run a load test on my Postgres database using tsung, and the reports were showing up as expected in the UI during the run. I am aware I can use a simple HTTP server to view the reports, but just wanted to report an error I came across while using tsung view:

root@tsung-0:~# tsung view
Starting Tsung web only on port 8091
{"init terminating in do_boot",{function_clause,[{filename,join,[{undef_var,template_path},"style"],[{file,"filename.erl"},{line,413}]},{ts_controller_sup,start_inets,2,[{file,"src/tsung_controller/ts_controller_sup.erl"},{line,108}]},{init,start_em,1,[]},{init,do_boot,3,[]}]}}
init terminating in do_boot ({function_clause,[{filename,join,[{},[]],[{},{}]},{ts_controller_sup,start_inets,2,[{},{}]},{init,start_em,1,[]},{init,do_boot,3,[]}]})

I've tried running this both in the tsung log directory (with report.html/index.html etc.) and in an unrelated empty dir, the error seems to be the same. Wondering if I'm missing an argument?
