This one is harder. I’ve found the cause, but it’s bedtime so I’ll have figure out what to fix tomorrow. The fundamental problem is that when I call “new KvpFrame” in sixtp-dom-parser.cpp, it’s allocating memory that libxml2 thinks belongs to it, so when the “data_for_children()” subtree is freed in gnc_book_slots_end_handler(), the frame belonging to that KvpValue gets freed and later overwritten by a call to g_log. When the optiondb tries to access later, boom.
