Upstream fixed via commit (https://github.com/ipython/ipython/commit/92309bb477e9ef2c1f912691285c985c8c35fdb5)

Provided in the comments are two attachments.. the actual patch and a patch for package-atom dev-python/ipython-0.13

Unfortunately, upon further review, the patch fixes the error (no traceback) but store is still broken.

I'll look at other upstream commits to find a complete solution.

I can reproduce this with 0.13 but not with 0.13.1

However I'm not sure how to restore it. If restoration is done with load, then loading doesn't work for me on 0.13.1.

[Comment 6 Jan Matějka (RETIRED) 2013-05-08 00:07:04 UTC]

fixed in 0.13.1-r1

In [1]: a=1

In [2]: store
Stored variables and their in-db values:

In [3]: store a
Stored 'a' (int)
