That seems to point to an invalid hash table in the book object, though I don't see in the code where that would happen. Regardless, try this: 
* Open a Finder window and select Go>Go to folder from the menu or press shift-command-g. 
* In the dialog type ~/Library/Application Support/Gnucash/books. 
* Find the file corresponding to your data file name with a .gcm extension, e.g. "my_file.gcm" and move it to Trash.
* Start GnuCash

I think you have an invoice tab open and something about its Tax Table listbox is causing GnuCash to crash. Removing the .gcm file will start GnuCash with only the Accounts tab and if I'm right will avoid the crash.
