OpenStudio crashing with IDF import (Versions 2.1, 2.5)

edit

When trying to import the IDF example file 1ZoneDataCenterCRAC_wPumpedDXCoolingCoil.idf, OS version 2.1 crashes altogether without any notice (EP 8.7 idf file version), and Sketchup-plugin fails to import the idf; OS 2.5. and Sketchup plugin produce the following error message with the EP 8.7. idf file version:

File at [....]1ZoneDataCenterCRAC_wPumpedDXCoolingCoil.idf is not valid to draft strictness 
 The collection is INVALID at strictness level 'Draft', because of the errors:

When trying to import the EP 8.9 idf version, OpenStudio 2.5 opens an message window with "unhandled exception".

Will software developers confirm and post an issue ?
