Details:

I am still investigating the source of the problem. For what I gathered, seems
to me that the origin of it is related on how events are handled and
transferred between the various components after creating a
detached/dissociated terminal.

If someone has more information about it please feel free to send a detailed
explanation to my email.

The patches here provide a workaround. As the webinfo/parse structure is
created before the octave interpreter running on a detached/dissociated
terminal is created, the unpacked documentation is redirected to a temporary
file from where it can be read without errors.

For some strange reason, the cleanup provided on parser class destructor is
never performed. My suspect is that the process is killed before it get a
chance to roll. An error code is always returned from octave-gui run so,
perhaps, there is something to be checked there also.

It should be noted that if you run octave from the development dir with
./run-octave, this problem will not show up as from there the parser routine
get the unpacked *.info files. Compact them before a ./run-octave issue and it
will be displayed.
