[Bug 1838538] [NEW] Gimp crash

Sender: bounces@xxxxxxxxxxxxx
Public bug reported:

Gimp crashed - fresh install.

1) I imported a pdf
2) made all layers except first hidden
3) selected a portion and wrote on it with a pen
4) hide first layer and tried to write on last - I couldn't do that as it was "active layer not visible"
5) selected a portion but still couldn't write
6) I put a lock on last layer and I could write on it (actually on all layers...)
7) I selected a different page and reselected everything (removed lock in the meantime) and after writing to it the program crashed

```
