Gnucash doesn't start anymore in Windows

[C. D.]

Hi,

something between r18248 and 18253 causes, that the gnucash nightly
build for Windows doesn't start anymore. I can see the Tip of the day
Box and some loading then it exits with code 2.

Under http://bugzilla.gnome.org/show_bug.cgi?id=591761#c1 you can find
most informations, additionaly I put the contents of the gnucash.trace
file in this mail.
