> It crashes when I click on "Export"

Still unclear to me - 'Export' as in menu 'Datei > Bitmap exportieren… Shift+Ctrl+E' (same as the 6th button on the commands bar)? Or do you open the 'Save as…' file dialog (menu 'Datei > Speichern unter…')?

Does this happen with a certain document only, or with new files as well?

Can you try to reset the preferences for the installed version and test if using Inkscape with default settings works again? The preferences file 'preferences.xml' is located in "%APPDATA%\Inkscape" (you can enter the string as is into the address bar of the Explorer). Please close all Inkscape instances, rename or move the current preferences file and restart Inkscape (the installed version). If that works ok, could you attach the "broken" preferences file to your bug report?
