1) created custom report "Income & Expenses Line Chart" covering all the years (used as a trend line) 2) Export --> Report --> CSV 3) When file name is confirmed, then GNU crashes, and keep locked the database.
I can confirm this on Windows. Not sure how to debug without inserting lots of tracer calls and waiting for a win32 nightly.
Ok I found the bug. Please insert the following line into net-charts.scm somewhere at the top near other use-modules: (use-modules (srfi srfi-26)) Alternatively try tomorrow 12-October onwards nightly in https://code.gnucash.org/builds/win32/maint/
