crash at schematic-opening - most probably worksheet dependent

Description

Loading all my older (>=5days) schematics results in a eeschema-crash.

This is most likely caused by the worksheet, as it's also impossible to change the worksheet (on a new created porject) to my specialized worksheet.

Steps to reproduce

1. open attached project (complete empty), open schematic: new_project_01.zip
2. File-->Page Settings-->Drawing Sheet--> select file "pagelayout_default_ibfeew_logo.kicad_wks" from project-directory
3. click OK to close Page settings: crash (the new wks-file was already saved into the project-settings)
4. from now on the schematic can't be opened anymore (this state is preserved in this project: new_project_01_crashed.zip
