Luckily there are not enough packages with exactly this problem that 
would inspire me enough to write a more specific bug template :-)

Correct. ECopyNPaste. (BTW: glx-diversions was another package I tried 
that had unsatisfied pre-depends and dpkg refused to unpack it.
(and no, adding a pre-depends is not the correct solution for this bug))

And now I have more good ideas to write a better bug report the next 
time I find such a mess :-)

I wheezy (just plain install, no upgrade from squeeze) I find (after 
filtering out the sendmail cruft)

python3-epr-dbg_0.6.1-2.log
0m22.4s INFO: dirname part contains a symlink:
  /usr/include/python3.2_d/numpy (python3-numpy) != /usr/include/python3.2dmu/numpy (?)

0m29.1s INFO: dirname part contains a symlink:

Hmm, the other don't show such traces in their logs, but three were tested:

ls: cannot access wheezy/main/*/python3-pygame_*.log: No such file or directory

There were no problems detected so far ...

Since there is no dependency from python-numpy to python*-dev*, everything is fine
(well, at least this piuparts test does not see a problem).
Good luck installing python*-dev* now :-(

Detecting these properly needs another tool ...

And more RC bugs to be filed ...
