kate (3.5.2) on KDE Platform 4.5.2 (KDE 4.5.2) "release 9" using Qt 4.6.3

- What I was doing when the application crashed:

I was able to reproduce this bug a few times. I was working on a document and hit ctrl-f to pull up find dialog, started typing a query and it autocompleted because I had used this query before, but I think I retyped the whole word anyway. I then hit ctrl-r to do find/replace, and it crashed. I opened the file again and did the same and it crashed again. Repeated once more before I did things differently to continue. I'm not able to reproduce anymore.

kwrite (4.5.1 (KDE 4.5.1)) on KDE Platform 4.5.1 (KDE 4.5.1) using Qt 4.7.0

- What I was doing when the application crashed:
After using the find dialog (ctrl+f) to search for strings, I pressed ctrl+r to start replacing words, triggering a crash in kwrite.
