bigdash.py screen turns blank

[lewis]

Run the bigdash plugin <alt-x> global-search. Enter a search term into the window: s foo
When you select any of the find hits the window goes completely blank and does not take the cursor the the selected node in the body pane.
I am running python 3.5.2 with PyQt5. Hopefully someone can test with PyQt4 and confirm if this only occurs with PyQt5.

Here is the console. The QTextBrowser messages appear after selection of the first and second results in the search window. You can repeat the search but the window always goes completely blank.

​Works for me with the following:

    Python 3.5.2, PyQt version 4.8.7

    Windows 10 AMD64 (build 10.0.14393) SP0

It fails with the following:

    Python 2.7.12, PyQt version 4.8.7

    Windows 10 AMD64 (build 10.0.14393) SP0

The user sees this in the console and in the log pane:

    loadOnePlugin: can not load enabled plugin: leo.plugins.bigdash

Tracing with g.pdb() shows the failure is in top-level init() function in bigdash.py:

This line:

    g.app._global_search = GlobalSearch()

throws:

    ValueError: 'unsupported pickle protocol: 4'
