Language file not found for the plugin 'ExamplePlugin'

[runtime57]

After completing a install of 0.4.1 i got the following error:

Language file not found for the plugin 'ExamplePlugin'. Backtrace:

#0 /home/content/r/u/n/runtime57/html/piwik/core/PluginsManager.php(179): Piwik_PluginsManager->loadTranslation(Object(Piwik_ExamplePlugin), 'en') #1 /home/content/r/u/n/runtime57/html/piwik/core/FrontController.php(232): Piwik_PluginsManager->postLoadPlugins() #2 /home/content/r/u/n/runtime57/html/piwik/index.php(57): Piwik_FrontController->init() #3 {main}

This works for me. PHP5.2.6 and 5.2.10.

Can you check that piwik/plugins/ExamplePlugin/lang/en.php exists and readable by the web server user?
