[bug #42782] Crash when loading a gorm file

[Yavor Doganov]

Follow-up Comment #6, bug #42782 (project gnustep):

Gorm doesn't crash now but it doesn't load the file either.  An alert panel is
shown with title "Alert" and "No information" as message.  The "image" file
is, oddly enough, data.info.  Here's the backtrace when this method is
reached:
