Bug 181894

Version:            (using KDE 4.1.96)
Compiler:          gcc version 4.2.1 (Apple Inc. build 5564) 
OS:                OS X
Installed from:    Compiled From Sources

Kate crashed while editing a Portfile and using the delete button. OS X.
The backtrace mentions something about  cursor. I noticed that the default black oxygen cursor was momentarily shown (a second if not shorter) instead of the default OS X cursor sometimes while going from the editing window to the documents sidebar. 
To reproduce I open a file with some text.
delete from the end of the document
Press "delete" key once more
Press left cursor key
Here's a video that shows it much better: http://www.youtube.com/watch?v=U8qOnxjNp6w
