#4 "Too many values to unpack" crash after failed emerge entry

[Robert Cernansky]

Version 3.0 crashes after click on a log entry of a failed emerge.

The traceback is:

Traceback (most recent call last):
  File "/usr/lib/python-exec/python3.6/elogviewer", line 219, in setEditorData
    editor.setHtml(model.itemFromIndex(index).html())
