Exception Notifier seems to have ceased working for some reason. I  
thought perhaps a change in edge rails was to blame, but I rolled back  
to 4900 and the problem was still there.

The problem is that it generates an error in the \_session.rhtml partial.

It looks as if a method in the PP class is bombing. It says wrong  
number of argument (1 for 0), but there is no method on that line with  
only 1 argument.

Any help is appreciated.

3: \* \<%= variable %\>: \<%=  
PP.pp(@request.session.instance\_variable\_get(variable),"").gsub(/\n/,  
"\n ").strip %\>  
4: \<% end -%\>

I had this problem on edge, but when I backed off to the most recent  
stable version it went away. Did you way what version of Rails you  
were running?

It seems to be fixed in the latest version of edge. Strange though as I  
rolled back to 4900 and still had the problem. Perhaps it’s been broken  
in edge for while?

Well it seems ok now. I’ll keep my fingers crossed.
