Tested again on Windows XP, Inkscape trunk revision 13511.
The dialog shows correctly in the task bar.
The fact that the dialog is modal is not a problem IMHO, but it should at least give some hints on how to fix the preferences file (or better, give the choice to recover from an autosaved or a default file - see https://blueprints.launchpad.net/inkscape/+spec/multiple-preferences-management) and report where in the file the error is (as it is already done when launching Inkscape from the console).
