Kate segmentation fault

Hi all,
I have frequent segmentation fault in Kate when I close an open document.

Just now, I opened Kate (from the CLI to capture the output), wrote a few random chars in the document, then clicked on the close button in the titlebar.
Kate prompted to save the document, I click “Discard” and then Kate segfaulted.

Here is the ouput:


cristiano@xmper8q3:~> kate

Any hints?

TIA
