Summary:

This is a very similar report to bug `34857430`.  The only difference is that this is now occurring on OSX 10.13.1 (17B48).  

If there is in fact a solution, please share. Otherwise, this is a report of the same bug on a new build of OSX.  The reported "solution" to this bug was to remove the `~/Library/Application\ Support/com.apple.backgroundtaskmanagementagent/backgrounditems.btm` file.

This worked, until after updating to 10.13.1.  Now, the `backgrounditems.btm` file is not present on my machine, therefore it can not be removed.

Steps to Reproduce:
same as `34857430`, except now on macOS 10.13.1

Expected Results:
same as `34857430`

Here is a truncated stack trace.  The same one (and similar ones) is available in the github issues link below.
