#1382 TypeError: expected a list.

Original ref is: http://stackoverflow.com/questions/36393896/gdcm-python-dicom-decompression

Basically the code generated is [1]. So one would need to s/list/tuple/g in the error message for clarity.

thx

This is an old bug tracker for SWIG which is no longer actively monitored (I only saw your ticket by chance). Please use the github tracker instead.

But this isn't a bug in SWIG anyway - the "expected a list." message isn't present in the SWIG source code and never has been - looks like it comes from a custom typemap gdcm specifies:
