Crash when trying to load corrupt file with NSDictionary -initWithContentsOfFile:

[Roland Schwingel]

Hi...

Recently I discovered a crash when trying to read a file which should 
contain a NSDictionary (using
-[NSDictionary initWithContentsOfFile:]) but instead contained 1736 
binary zero bytes (hex 0x00).
GNUstep crashed badly when doing this instead of discovering that it 
contains nothing parseable.

Attached you will find my small patch to fix this. When deserializing it 
is always checked whether the
GSIArray is used or not but not in one case. Added an if to solve this. 
Now when trying to read this
corrupt file I get a correct NSWarnLog() that it does not contain a 
valid dictionary.

Hope this patch can be applied

Roland
