Looks like a zero-divide error. I'm trying to pick through this with
gdb to print the gnucash transaction. I can't work on this much longer
today as I have other committments. I'll get back if I learn anything
worth reporting.

One other thing -- with the built-from-source version, I get KNotify
crashes, such as when I click File->Import->Gnucash:

Phonon::GStreamer::Backend: Failed to initialize GStreamer
WARNING: Phonon::createPath: Cannot connect  Phonon::MediaObject ( no
