[New-bugs-announce] [issue15111] Wrong ImportError message with importlib

[Amaury Forgeot d'Arc]

New submission from Amaury Forgeot d'Arc <amauryfa at gmail.com>:

Up to Python3.2, a nested ImportError was correctly displayed:

./python -c "import distutils.msvc9compiler"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/amauryfa/python/cpython3.2/Lib/distutils/msvc9compiler.py", line 27, in <module>
    import winreg
ImportError: No module named winreg

But with 3.3, the traceback is lost:

~/python/cpython3.x$ ./python -c "from distutils import msvc9compiler"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: cannot import name msvc9compiler

Even though the failure is still on the "import winreg" line. Only ImportError seems affected, other exceptions are correctly displayed.
