           Summary: VIEWING: Caused Xorg 100% CPU and the whole GUI hanged
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)

Problem description:

When browsing the attached file, at some point (pages), Writer hanged, and the
whole GUI system hanged, so I had to switch to the console TTY1 to do
something.

In program 'top', it showed that 'Xorg' occupied 100% CPU.  After killing
Writer, the whole system returned to the normal state.

----
I tested it in MS Windows XP, LO will hang itself in certain pages, but won't
hang the whole system.  The hang pages differs from that on GNU/Linux.
----

Apache OpenOffice 4.0.1 doesn't have this problem; we can browse the file very
smoothly wih OO.

With this problem, no one dare adopt LO as normal office tool in serious
business, because the attached file is a normal file created with MS Word
without any trick.

--------
TEST CASE 1 (browsing)
--------
Steps to reproduce:
1. Open the attached file, and page down to browse it.
2. For LO 4.2.1.1, it hangs in page 8.  For previous versions of LO (I tested
4.1.4 and 4.0.6), it hangs in page 4.

Current behavior:
LO causes Xorg to run at 100% of CPU and the whole GNOME hangs.

Expected behavior:
LO should view the file smoothly without hang the whole GNOME GUI.

--------
TEST CASE 2 (save as ODT)
--------
Steps to reproduce:
1. Open the attached file, "Save as..." as ODT format.

Current behavior:
LO causes Xorg to run at 100% of CPU and the whole GNOME hangs.
But it seems that the odt file can be saved completely.

Expected behavior:
LO should not hang the whole GNOME GUI.

--------
TEST CASE 3 (good behavior for exporting to PDF)
--------
Open the attached file, and export it to PDF format.  It behaves correctly.
Operating System: Debian
Version: 4.2.1.1 release
