Continuous Exception ... What does this mean?

Today I changed some resources in my RC files (more precisely, I replaced the PNG file with another one and then rebuilt the RES file with BRCC32). After restoring my application, I tried to start it but got the following exception:

Project Blablabla.exe raised exception class $C00000025 with message non-continuable exception at address blablabla...

      

        
        
        
      

    

I am using madExcept, but this exception was not handled by it, but rather by the internal Delphi exception handler. The event log window shows that this exception is being thrown on my main thread. My only resort was to replace the suspicious PNG file with the original one. What is this exception? What can't go on? Application load? Reading resources? Loading DLL / packages? Somebody knows? Google is not good to me today ...
