6305	AttributeError: 'bool' object has no attribute 'lower'	anonymous	bobbysmith007	"after installing the plugin i can't create a new ticket, i get the following error :

Oops…
Trac detected an internal error: AttributeError: 'bool' object has no attribute 'lower'
This is probably a local installation issue. 

Found a bug in Trac?
If you think this should work and you can reproduce the problem, you should consider reporting this to the Trac team.

Before you do that, though, please first try searching for similar issues, as it is quite likely that this problem has been reported before. For questions about installation and configuration of Trac, please try the mailing list instead of filing a ticket. 

Otherwise, please    
==== How to Reproduce ====
