NSString ? bug

[Enrico Sersale]

With the today cvs, if you try to open two files with their default
application, the first time the application is launced and the file
opened, the second time the app crashes immediately after showing the
window of the second file. Sometimes also gdnc dies. (hope this is
understable...)

Better an example:

gopen HandOpen.xpm

ImageViewer is launced and HandOpen.xpm shown.

gopen Unknown.xpm

Unknown.xpm is shown and, after, ImageViewer crashes with:
