Comment 1 hanya 2015-01-01 15:14:51 UTC
The IndexOutOfBoundsException is raised in SwAccessibleContext::getAccessibleChild method. 
The method is called in "for" statement of FindFocus function in gtkframe.cxx for Gtk environment. 
The getAccessibleChild method is called with illegal index and uncaught exception is reported as the fatal error. 
The number of valid accessible children is changed while the transition of the 
shown part of the page.

Here is the part of backtrace:

Comment 2 Regina Henschel 2015-01-01 19:09:47 UTC
Hi hanya, I cannot reproduce the problem on Windows 7, but I remember the similar issue 125971. Besides using Linux, are there other special settings or applied technology?
Comment 3 hanya 2015-01-03 12:39:06 UTC
I could not reproduce the problem on Xubuntu 14.04 64bit installed in VirtualBox 
without any input method installed.
After I installed "fcitx" input method framework, I could reproduce the problem. 
When I set to not use any input method through im-config, not reproduced.

Proposed patch to catch the exception

The problem is happen if input method is enabled like described in the above comment. 
IsAccessible state can be changed even in the loop, the exception have to be caught. 
With this patch, the input method should work well on Writer document.

Reviewed, accepted as blocker, fixes a fatal error and also has duplicates.

@hanya: feel free to port this from trunk to the AOO410 branch for OpenOffice 4.1.2. I can do it too, of course; as you prefer.
