[Rd] question about try and errors

I am using try. I have found that sometimes errors are not caught by
try. For example, I got the following error message from code that was
wrapped in try. After the error, my R CMD BATCH aborted.
Error in assign(".target", method at target, envir = envir) :
no function to return from, jumping to top level
Calls: reverseComplement -> loadMethod -> loadMethod -> assign
This specific error is in relation to the emails posted by Herve about
problems with the methods package (I think), and it also happens
inside a large piece of code that takes several hours to execute. So
it is not easy to give a reproducible example.
I am however surprised by the fact that try does not catch all errors
- are there different error levels in R?
