If you install do the following steps:
- Install a B1 Web Client Extension
- Use the Web Client's homepage customization tools to move the extension to the Home screen and exit Edit Mode
- Remove the Extension that was added on the home Screen
Doing the above results in the Web-Client "Crash" when reloaded with the following error
Error: while trying to read the field 'bind' of a null object loaded from field com.sap.b1.infra.meta.tile.Tile.action of an object loaded from local variable 'tile'
