[Python-apps-team] Bug#902784: cython-dbg: StringIOTree debug module missing

[Tristan Seligmann]

Package: cython-dbg
Version: 0.28.2-4
Severity: important

cython ships a StringIOTree extension module:

/usr/lib/python2.7/dist-packages/Cython/StringIOTree.x86_64-linux-gnu.so

However, cython-dbg is missing the debug version of this module. This results
in import errors when using the debug interpreter:

mithrandi at lorien ~> python-dbg -c 'import Cython.Compiler.Main'
