Strange. Are you sure TeXworks can't be used as PDF file viewer? On OS  
X it can, I just tried (ie dropping a random PDF file onto it). There  
are some warnings issued to the console, but they're harmless and the  
user doesn't see them, I only saw them because I opened Console.app to  
check:

That said, the original poster's request was different and mentioned  
compiling (a .tex input file in the Source window most likely),  
generating PDF output and then attempting to open this output (in the  
Preview window most likely):

Though not 100% sure, I would interpret this as normal TeXworks  
operation: open an input file in the Source window, typeset it and  
then view the result in the Preview window. And interpret the bug  
report as "memory could not be read" error, followed by program crash,  
when the Preview window is opened.
