I've mostly seen that error occur when two different variables are mapped 
to the same filename.

Most simply something like file a <"foo">; file b <"foo">; but less 
obviously in cases where mappers are used inside loops but not 
parameterised by the iteration variables of all containing loops (eg.

for a in [1:5] { file a <"foo">; ... }

maps the file "foo" 5 times to different variables (variable a in 5 
different variable scopes, one for each iteration of the foreach).

Sounds strange. Can you post the code here?
