Original Launchpad bug 306805: https://bugs.launchpad.net/ipython/+bug/306805
Reported by: fdo.perez (Fernando Perez).
Original report by Robin on the ipython user list is below.
I see the problem by using dreload(), but I can't reproduce it by manually calling the pieces of the code that break in that traceback. Will need to investigate further; there's a slim chance it's a problem in numpy's machinery that tries to detect that it's being imported from the build directory.

Subject: [IPython-user] dreload numpy - source dir error
To: "ipython-user@scipy.org" ipython-user@scipy.org
Hi,
I thought I had seen this come up but I can't find it - so sorry if it has...
I have an error using dreload with numpy... I get the error about
importing numpy in the source directory whenever I try to dreload
something that uses numpy. For the most part it does seem to work (I'm
not changing numpy - its my own code I'm trying to dreload) but the
long trace back is a bit annoying because it breaks the list of
results when scrolling through the history...
Anyway here is an example:
