Comment 1 Dario Andres 2009-12-06 23:46:45 UTC 
Looks like an error in the Qt library font handling.

I could not reproduce the issue here using:

Qt: 4.6.0 (kde-qt master commit cd8595efe9aace2afdaa5db37af7cfe82b87e4aa
        Date:   Wed Nov 18 01:33:21 2009 +0100)
KDE Development Platform: 4.3.80 (KDE 4.3.80 (KDE 4.4 Beta1))
kdelibs svn rev. 1058633 / kdebase svn rev. 1058634
on ArchLinux i686 - Kernel 2.6.31.6

Using Konqueror or Rekonq(webkit from Qt)

May be you have some missing font ?

- Try checking the same page on some Qt only browser ("Arora", "Rekonq")

Thanks
Comment 2 Densetsu no Ero-sennin 2009-12-11 08:48:14 UTC 
Arora crashes with:

arora: ../3rdparty/harfbuzz/src/harfbuzz-shaper.cpp:436: void HB_HeuristicSetGlyphAttributes(HB_ShaperItem*): Assertion `item->num_glyphs <= length' failed.

I think I have all the necessary fonts, because Firefox displays Hebrew texts at the same pages correctly.

Can it be a Gentoo bug?
Comment 3 Eugene Shalygin 2009-12-13 15:32:12 UTC 
(In reply to comment #2)
> Can it be a Gentoo bug?

There is a Qt bug: http://bugreports.qt.nokia.com/browse/QTBUG-6436
Comment 4 Dario Andres 2009-12-14 01:01:15 UTC 
It seems to be the same...
In any case it is a bug deep in Qt code, nothing that KDE could touch. Closing as UPSTREAM. Thanks
