Crash of 2.2.9 after install of 2.3.9

[M Prindle]

I installed 2.3.9 tonight to see the changes and test it out.  I opened 
my XML data file in 2.3.9, closed it, and then opened it in 2.2.9, but 
when it gets to business-gnome 2.2.9 crashes with Unspecified Fatal 
error encountered, aborting.  The error is a C++ error in gnucash-bin.exe.

If I open 2.3.9 it launches with no errors.

My main install is in program files\gnucash and 239 is in program 
files\gnucash239.

Running XP SP3
