This has remained quite reproducible for me with 2.2.9-7~squeeze1. The
trick is to let a few backup/log files accumulate over a few days, then
save the account file.
I did so with --debug bug saw no output other than the usual message
about binreloc relocation support.
The last time I tried to debug this I used strace and got the following
output while saving the account file:

As far as I can tell from that output, Gnucash is doing the right thing:
writing to temporary file, unlinking destination file, linking temporary
file to destination file (successfully!) and finally deleting the
temporary file. And yet, the result is that gnucash.xac is deleted.

Next time I'll try ltrace to see what strptime returns.
