DrawerLayout exception when 2 rows simultaneously dragged

I am using this library inside an application containing a DrawerLayout .
When I try to swipe 2 rows at a same time, it causes an exception on the drawer :

java.lang.ArrayIndexOutOfBoundsException: length=1; index=1
at android.support.v4.widget.ViewDragHelper.shouldInterceptTouchEvent(ViewDragHelper.java:1011)
at android.support.v4.widget.DrawerLayout.onInterceptTouchEvent(DrawerLayout.java:1111)

It appears that it is caused by the call of requestDisallowInterceptTouchEvent(true) on the parent layout

for more details of the issue and a possible workaround, check this link :

Why does your library need to call requestDisallowInterceptTouchEvent ?
