-- Information about the crash:
- This crash has happened multiple times, in either a case where:
  - I have multiple tabs open and click the [x] button
  - I have closed all but one empty tab and then click the [x] button

I have had Kate crash similarly with only Kate open on the desktop, or with all of my standard applications open.  It happens every time I have closed kate in the past couple of weeks.

The crash can be reproduced every time.

-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
