After import a sculpty from file system generic sculpties are no longer selectable.

I started with testing the default shapes. (OK).

Then i tried to load a sculpty from file. (OK).

Then i trieds another sculpty from file. (OK).

I tried to change parameters for file based sculpties. (OK).

Then i wanted to build something out of a cylinder. (FAIL).

I can no longer select basic objects after i have successfully used the file importer.

in the command window i see

bad menu entry index "<fileName>"

Where <fileName> is the full path to the last imported sculptmap.

After restarting blender, i can again select basic shapes until i import the next sculpty from file.
