SeleniumRc - Firefox fails to start

I am using Selenium-Rc 1.0.3 with Firefox 3.6.8. I started Selenium-Rc with -firefoxProfileTemplate option after creating a different Firefox profile for it. Each time I start the test and check the server-side log, I get this error;

Please, any idea on how to solve this? I will appreciate every helpful suggestion.

run selenium server in interactive mode . so just run this command java -jar selenium-server-jar -interactive -singleWindow

I also had this problem in Ubuntu. Temporarily launching the selenium server as root did the trick for me:

sudo java -jar selenium-server.jar
