How can I interpret the information within a Blender traceback?

A traceback reads from bottom to top. The last lines show the immediate error. Lines above detail the functions called to reach that point. Look for your own scripts or add-ons in the traceback – these are often the source of the issue. Pay attention to file names and line numbers; these pinpoint the exact location of the error. 'File "...", line X, in ...' is the key format.
