New crash information added by DrKonqi

kontact (4.4.6) on KDE Platform 4.5.1 (KDE 4.5.1) using Qt 4.7.0

- What I was doing when the application crashed:

as above - try to change the sidebar settings and kontact crashes. ie: select
small icons. Note, though, that I was able to reproduce the bug on the first
try - but not the second. On the third try Kontact crashed immediately - before
starting. will attach that report to this one.
