SIGSEGV in NSEPSImageRep imageRepWithData

Dear list,

I try to load some EPS files and save them as JPG. That works fine for
almost all of the files. Almost. One file is leading to the following
exception.

Exception:  EXC_BAD_ACCESS (0x0001)
Codes:      KERN_INVALID_ADDRESS (0x0001) at 0x002df000

Thread 0 Crashed:
0  libSystem.B.dylib           0x90006e40 strlen + 0x20
1  libSystem.B.dylib           0x90016e68 sscanf + 0x68

+ 0x78
4  com.apple.AppKit             0x9305e1c4 +[NSEPSImageRep
imageRepWithData:] + 0x38

The same problem happens, when I drag&drop the file into Mail: Mail
crashes.
The Preview-Application can open the file just fine (it converts it
somehow in PDF in displays it), so they go a different route than
NSEPSImageRep.

I tried to put an exception handler around the calling code:

NS_DURING
   returnImageRep = [NSEPSImageRep imageRepWithData: currentData];
NS_HANDLER
   returnImageRep = nil;
   NSLog(@"SOMETHING BAD HAPPENED");
NS_ENDHANDLER

but that did not help either.

My question: Is there something I can do to work around? It would be
great e.g. to copy that "bad" file into a qurantaine-folder and writing
a log message.

Thanks for any hints,
Stefan
