When running my klz_majoron_limits script on the QMUL machines I kept encountering this error (shortened slightly because it was rather unwieldy):

but not getting the error when running the same script (at the same commit) with the same version of python (2.7.6) on my laptop.
I am not sure of the cause of this, but it can be avoided by using copy.copy instead of copy.deepcopy.
The motivation for using deepcopy on spectra was that it copies all member objects e.g. instances of SpectraConfig, SpectraFitConfig, RateParameter, etc. as well so that if these are modified in the copy, the original would remain un-affected. However, on further thought, within the Fit class, the only instances that should be altered are FitParameter and derived classes. For fixed backgrounds these do not exist anyway (because they are fixed), so I think it should be safe to change the two instances here and here to just copy.copy.
