Hi all,

Whilst trying to load a certain article, knode crashes. It is reproducable.

The article in question is found on the news.gmane.org servers: gnome.hackers/Re: Subversion on container/Ross Golder/5th November 2005 18:40.

It is possibly this email: http://mail.gnome.org/archives/gnome-hackers/2005-November/msg00000.html

Here is the terminal output with embedded backtrace:

knode: KNMainWidget::slotArticleSelected(QListViewItem *i)

Are you using the experimental fontconfig patch from qt-copy/patches? In this case, this is a duplicate of #119108.

Yes, the kdesvn-build automatically applies the patches. I have just 
recompiled - it works fine now!

Also I think it applies to https://bugs.kde.org/show_bug.cgi?id=119194

That message doesn't crash anymore either.

Thanks,

Matthew
