The code in webrat/core/logging.rb creates a log file in the
current directory if the environment it is running under is not
rails or merb. This leads to problems when that log file cannot be
created.
This happens to me when using cucumber-nagios in a restricted
environment where nagios can execute the plugin but not write the
associated directory. The plugin fails because it cannot write the
webrat.log file. I've verified that this is the problem by
commenting out the only user of the logger in core/session.rb.
A solution would be to only create the log file when requested
(e.g. using an environment variable)
