Description of problem:
Gnucash can't create any reports.  Once attempted, the menus and toolbar become
unaccessible.  ~/.gnucash/books/<book> must be edited to remove reference to the
report before gnucash will restart normally.

Version-Release number of selected component (if applicable):
gnucash-1.9.5-3

How reproducible:
always

Steps to Reproduce:
1. Select any report, like "Balance Sheet" or "Cash Flow"
2. gnucash the issues scheme error messages on syserr (to be attached)
3.
  
Actual results:
Menus and toolbar are grayed-out and inaccessible.

Report tab has:
    Report error
    An error occurred while running the report.

Expected results:
Report being created.

Additional info:
I can't go back to 1.9.5-1 because of the guile upgrade (well, not easily).
