Body
This happens to a function in an imported module that is still executing after that module is garbage collected. Since your code isn't enough to reproduce the issue, here's a simplified example that shows the behaviour. Create a file containing the following and import it either from the Python command line or from another file. It doesn't work if you just run it at the top level. <pre><code>import sys import threading x = "foo" def run(): while True: print "%s %s\n" % (sys, x) threading.Thread(target = run).start() sys.stdin.readline() </code></pre> Running it: <pre><code>$ python >>> import evil_threading <module 'sys' (built-in)> foo <module 'sys' (built-in)> foo ... press Ctrl-C None None None None ... press Ctrl-\ to kill the Python interpreter </code></pre> During Python shutdown, modules are set to <code>None</code>. <a href="https://stackoverflow.com/q/25649676/509706">This is an obscure Python behaviour that was removed in 3.4</a>. In this example, terminating the main thread results in shutdown, but the other thread is still running, so it sees the modules as <code>None</code>. There is a simpler example <a href="http://grokbase.com/t/python/python-list/035r7sjsnj/module-gets-garbage-collected-its-globals-become-none" rel="nofollow noreferrer">from here</a> which does the same thing by deleting the module reference directly from sys.modules. <pre><code>import sys print sys del sys.modules['__main__'] print sys </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
