KDevelop crashes when switch from vi-mode to Normal after a search and/or replace is performed. I'm unsure if it's a Kate bug or KDevelop, but the crash cannot be reproduced with the same steps for KDevelop on Kate.

Reproducible: Always

Steps to Reproduce:
1. Open any file.
2. Search and/or replace.
3. Switch between Normal/vi-mode, although my observation is that it crashes when switching from vi-mode to Normal.

Actual Results:  
KDevelop crashes
