Bug 15b4 "Delete Shared Node" crashes Resolve

On the color page, right clicking any node, going to "Delete Shared Node" and then select a shared node to be deleted, freezes Resolve for about 20 seconds and the exits without any error message.
It is only a 7 minutes timeline. I use 4 different shared nodes and wanted to delete a 5th that was not relevant any more.
I went through all clips on the timeline to check if the 5th shared node is used in any of them.
I can work without problem with the unused shared node,
just helping to de-bug.
