FreeCAD crashes when deleting kitchen cabinet

[j-hap]

Steps to reproduce:

• Open FreeCAD 1.0.0
• Switch to BIM
• Create a new Document
• Open Object Library Browser
• Insert vertical kitchen cabinet
• Delete the just inserted cabinet
• FreeCAD crashes

Demo:

It probably is a bug in FreeCAD itself, but it is triggered by the component in the library, so I'm not sure if the issue should be here or in the FreeCAD project.

[bitbasher]

i was able to add a vertical cabinet from the library in a dev version of FC that I am playing with right now. I saw a lot of interesting warnings in the report panel as it was added .. this is the pastebin link to see them all.

a possible factor .. i had a message about a git related "thing" not being installed,
here are the first few notifications :

12:25:26  BIM workbench activated
12:26:08  Unit system updated for active document
12:27:08  python-git not found. Git-related functions will be disabled
12:27:49  Loading Spreadsheet module... done
12:27:49  Loading GUI of Spreadsheet module... done
12:27:49  <ElementMap> C:/Users/Jeff/AppData/Roaming/FreeCAD/Macro/PartsLibrary.FCMacro(266): Invalid element name string id
12:27:49  <ElementMap> C:/Users/Jeff/AppData/Roaming/FreeCAD/Macro/PartsLibrary.FCMacro(266): Missing element name prefix id

--
then came several hundred more warnings that you can see in the pastebin file.

I open the vertical cabinet file in my dev version of FreeCAD into an empty document .. NOT in the BIM workbench, and i get all the same warnings. I save it into a new document elsewhere. I rename the existing vertical cabinet file to hide it, then copy in my just saved file.
Now I start a new BIM document, so i am in the BIM workbench, open the library selector and bring in my updated vertical cabinet file .. no warning messages. I try to delete it and get a TON of errors and warnings and only parts of it actually delete .. it leaves a horrible mess in the Model Tree.
The original file is still visible in the Kitchen directory so i try to bring it in again .. and boom .. all of the original problems show.

So it looks like the .FCStd files in the Library will all have to be updated. Ouch
