Runtime exception but where to start debugging?

[claj]

Two projects have "rot" for me in the sense I cannot run "lein marg" any longer, and it does not give a very clever error message either.

The error I get is the following:

$ lein marg Generating uberdoc for the following source files: /Users/linus/Documents/code/dspanel/rulator/./src/clojure/contrib/zip_filter/xml.clj /Users/linus/Documents/code/dspanel/rulator/./src/clojure/contrib/zip_filter.clj /Users/linus/Documents/code/dspanel/rulator/./src/rulator/email.clj /Users/linus/Documents/code/dspanel/rulator/./src/rulator/models/rules.clj /Users/linus/Documents/code/dspanel/rulator/./src/rulator/models/user.clj /Users/linus/Documents/code/dspanel/rulator/./src/rulator/server.clj /Users/linus/Documents/code/dspanel/rulator/./src/rulator/views/common.clj /Users/linus/Documents/code/dspanel/rulator/./src/rulator/views/editor.clj

Where do I start debugging that? Or rather, would it be possible for marginalia to print in which file it got into problems?
