Version:            (using KDE 4.3.2)
OS:                Linux
Installed from:    Ubuntu Packages

What I was doing when the application crashed:
1) Messages list looked like this:
  other email
- thread1-a
     thread1-b "SELECTED"
        thread1-c
  other email

2) I collapsed thread1 with thread1-b selected:
  other email
+ thread1-a
  other email

(Nothing got selected, thread1-a should have)


3) Pressed key delete. CRASH.
