Hi all,
I am trying to solve problems with Orca screen reader on Opensuse 11.1 on my sisters laptop (HP 550 with Celeron, Intel graphics and 1GB ram).

Today I worked a little bit with her machine and found out that sometimes, some native gnome apps accidentally use up to 100% CPU and then cause freeze or crash. I saw it today with Nautilus, Gnome panel or Gnome ICU. I do not think this is normal. Is there any way to find out where is the problem?

In xsession errors I found this but I do not know if this is related to this problem:

Code:

I first though that the problems - some system sounds not working (email notification in evolution etc., audio/video in totem is ok, startup sound also), Orca instable and slow; was caused by pulse-audio, but now it looks like there is another problem.

I added full hardware info from Yast here:

Send big files the easy way. Files too large for email attachments? No problem!

It would be great if anybody could give me na advice to solve the problem.

PS: is it normal, that Firefox (version 3.0.8) takes about 60% CPU when only browsing normal web pages (no youtube, no video, adblock is active) with about 7 panels opened?
