Trying to recover from corrupted files - not going well.

[marc+gnucash at milestonerdl.com]

My gnucash install has now went off the rails :-(   I wanted the bill import section so that
means compile trunk from scratch and include --with-python

Under 2012-1-14 version of trunk there was an export as XML.  Today's trunk r22201 no longer has that export as XML but export as CVS.   How can I get past this data corruption issue and export/import the dataset in trunk?

The 2011 version was broken where billing importing was hit and miss - known bug.
The 2012-1-14 version worked for a while, then after various linux system upgrades at some point when I returned to entering stuff in the accounting system when I save a file the saved file is not openable.  I just did another grab of trunk and did a save from a working file and get a non-working file.   The below is an example from the trace file of a:

$ gnucash gnuworked2
(within GnuCash File -> Save As gnuborked)
$ date;gnucash gnuborked.gnucash
Thu May 24 11:57:47 CDT 2012


This is a development version. It may or may not work.

the Python warning doesn't make sense to me either:
