Description

after upgrading from 1.2.7 to 1.3.1 I ran into error messages like "cannot import name XY". I had to use the PDB lib and heavy debugging to find out why. It should print the error source.

I found out:
in /django/core/management/base.py:206-207

that

import traceback
sys.stderr.write("%s" % traceback.print_tb(sys.exc_info()[2]))

helped a lot to tell me about the errors source.

You are right in that masking exceptions is a bad thing. We are trying to improve the situation (see for example #18845). However, we have already improved things in current code, notably with [694bc0f22bdb30a472de6fec05a44adf5c0f1f2c] and [f2b6763ad7cb281ca8699a9c3d532a82f965be4f]. If you find something that's still not good enough in current code, feel free to reopen with a real case.
