           Summary: radeon [XPRESS 200M] OpenOffice crashes X server when

Created an attachment (id=38480)
 --> (https://bugs.freedesktop.org/attachment.cgi?id=38480)
sample document which can cause OOo to crash (last footnote)

When hovering over a reference to a footnote, a preview appears. However, when
the footnote is long (> 4 lines), the preview is distorted (something I can
live with), and when it is very long (7 lines or more) OpenOffice crashes,
taking with it the whole X server. This happens also with a clean user
directory, so no corrupted personal settings.
I just found a Ubuntu bug report:
https://bugs.launchpad.net/ubuntu/+source/openoffice.org/+bug/606602. Compiz
actually reports "text length exceeded". It seems to be the same issue: OOo
doesn't line-break in footnote previews - if the preview is
much too long for one line, OOo does _something_ which 
-in Gome with Compiz (there's no information about the graphics) crashes
Compiz,
-in XFCE with Compiz and proprietary Nvidia driver leaves just an empty
tooltip,
-in KDE SC with KWin and free radeon driver crashes X.

It's very annoying, because in my scientific writings I have a lot of long
footnotes and every now and then OOo crashes. It took me weeks to find out the
reason.

OpenSuse 11.3, KDE SC 4.5.0, Kernel 2.6.34-12, ATI Radeon XPRESS 200M with
radeon driver

For comparison I tested OO.org on my other machine with an NVidia card: On
Windows everything is shown correctly, on XFCE longer previews (from 4 lines
on) are displayed as withe fields, but no crash.

I've reported this to Novell Bugzilla, but for the lack of ATI Xpress hardware
they can't debug it there.

I attach an example file and the debug output.
