Another Java related Segmentation violation on WinXP

[Tribo Laboy]

Hi!

I am having a hard time to troubleshoot Java-related segfault of
Octave on Windows with JHandles backend.
I am using a modified textread.m file from FileExchange, in which I
have tried to remove all calls to graphic routines (it uses a
waitbar).
Sometimes the program runs just fine and imports the data into a cell
array as it is supposed to do. Sometimes it fails miserably and
complains about Java. I really can't understand where does this come
from.

I have uploaded my modified copy of textread.m here:
tribolaboy.googlepages.com/octave_stuff

The execution of the comands and the trace of the segfault are shown below.

Anyone can help?
