Comment 2 Allen Winter 2012-08-28 21:40:57 UTC 
Tommy,

Since you are self-compiling, would you feel like doing a test?
I can't reproduce this.

If you can test, in kdepim/akregator/src/articlelistview.cpp
please add the conditional
if(model()) on line 323 immediately before the call to startResizingTitleColumn()

let me know either way,
Allen

Git commit 84368d12a05445aaf511f657f6d00535060d7204 by Allen Winter.
Committed on 30/08/2012 at 22:50.
Pushed by winterz into branch 'KDE/4.9'.

in restoreHeaderState(), make sure there is a model before attempting
to resize the title column.
FIXED-IN: 4.9.1
