wsod after implementing

First of all i think this is a potentially great module. there are some errors still however:

configuring a breadcrumb which displays a taxonomy term belonging to the node on a node page causes a WSOD (500 error aamof)

I created a hansel breadcrumb for an 'information article'. The path of the node might look like:
mysite/informacion/legal/laws/law-lorem-ipsum

the 'information' node has a taxonomy term which defines the 'group of articles' the node belongs to. the group of articles is a taxonomy vocabulary with hierarchical terms. So LEGAL is parent term of LAWS.

My 'Hansel hierarchy is like this':

• 1. start
  add link inicio
  switch on path alias (starts with)
  admin
  leave (restore original breadcrumbs)
• 2. blog
  leave (restore original breadcrumbs)
• 3. foros
  leave (restore original breadcrumbs)
• informacion
  add link información
  • switch on url argument 1
    node
    Add term path using the vocabulary Grupo de artículos (información)
    leave

So in short: i check for the path, if the path is 'informacion', i check if its a node, and then i want to output a link to the taxonomy term belonging to the node.

I hope this information helps,
