[Gvsig_english] Problem gvSIG 2.0.0.2066 -- Program crashes when opening ECW file

[Cèsar Ordiñana]

Hi Simon,

I think we have found a temporary solution. It seems the crash is 
produced because of a bug in the native library we use to load the ECW 
files. I've been looking and it is also happening in the last linux 
distributions when you use gdal to open an ECW file:

http://osgeo-org.1560.x6.nabble.com/ECW-support-on-Fedora-Linux-error-td4991388.html

One of the developers on that discussion found a very easy way to avoid 
the problem, by setting the environment variable NCS_USER_PREFS to point 
to some bogus file name. I have just updated to Ubuntu 13.04 and had the 
same crash opening ECW files, but by setting the environment variable it 
works again.

If you want to try it just edit the "gvSIG.sh" file in your gvSIG 2.0 
installation, go to the line 144 (after the "export LC_NUMERIC=C") and 
add a new line with the following text:

export NCS_USER_PREFS=/tmp/dummy

Then save the file and run gvSIG to check if it works for you.
