Good news: Filed an abiword bug, and was able to narrow down the source of the problem, giving steps to reproduce, creating a thesis about the source of the bug, and successfully testing the thesis, like a good bug filer should.
Bad news: A 1.5M, 143 page document is not really an ideal minimal testcase.
Worse news: I’d have preferred to notice this kind of bug before I created two 140+ page documents that trigger the bug.
[Yes, those are my collected, organized class notes, one class each. Tomorrow, rinse and repeat with Civil Procedure.]
