If you render an arabic string when using justification, the glyphs are all
pretty wrong.  Test case coming up.

Attachment: test case for arabic

This test case uses text-align: right to trigger the justification code.

Comment 2

[Robert O'Callahan (:roc) (email my personal email if necessary)]

justification usually means 'text-align:justify'

Comment 3

[kobi zamir]

text-align:justify with pango mess up hebrew as well.

Does this bug still occur in a recent trunk build?

Yes the bug still occur with the build:
"Mozilla/5.0 (X11; U; Linux i686 (x86_64); en-US; rv:1.9a6pre) Gecko/20070617 Minefield/3.0a6pre"

But I checked with the firefox version that come with Fedora 6:
"Mozilla/5.0 (X11; U; Linux x86_64; fr; rv:1.8.0.10) Gecko/20070313 Fedora/1.5.0.10-5.fc6 Firefox/1.5.0.10"
and the test case rendred correctly.

I'm using the exact same build (20070617) and it seems to work fine for me.
Amaoui, could you attach a screenshot of the error please?
Also, what does the menu View->Character Encoding say it is?
Which font preferences are you using? (a screenshot of the Preferences->
Content->Font&Colors:Advanced dialog would help)

This bug as reported is now WORKSFORME. (We have bug 635639 with some fonts, but it doesn't depend on justification)
