My QIF file crashes GnuCash. How can I find out what line(s) it doesn't like? (Corrected)

[Pat McGee]

I tried to import a QIF file from the Mac version of Quicken 2000 into  
GnuCash 2.2.9 (Mac Intel version). The druid goes through several  
screens, the last one being ***Currency selector*** (corrected from  
Payees and Memos). As soon as I click on the Forward button, the  
program crashes.

In the Console log, I see the message I've appended below.

The qif file is about 1.4 MB. So, I'm reluctant to start making  
changes without more clues as to which parts I should work on.

How can I figure out what line(s) the QIF importer doesn't like?

(If it helps, I have programmed some in LISP, but I'm not really good  
at it. I'm pretty good at C and Objective-C, amongst others.)

Thanks,

Pat
