Yes, there is a bug in kate. If you do the following:
1. open file in kate
2. select "save as" and save in a different file name
3. select "save as" again and it will crash
It will crash on the second "save as".
For me it is 100% reproduceable. I am using kde 3.0.0 and qt 3.0.3. I don't 
know if it was fixed already in the branch and/or head, and currently don't 
have enough time to check this.
