Backtrace
SUMMARY
Kate crashes when closing a file that was deleted externally. I went through
the "Report bug" steps, but the wizard claimed the report was not useful,
unless I installed the debugging symbols. It could only install the first
debugging symbols bundle/library, and the other three failed with:
```

```
Given that failure, I'm attaching the backtrace directly.
STEPS TO REPRODUCE
1. `echo 1 > bug.txt`
2. `kate bug.txt`
3. `rm bug.txt`
4. Switch to Kate, which should detect the file having been deleted
5. Click the "Close" button
OBSERVED RESULT
Kate crashes
