Crash when opening specific secondary shared cache file

[emesare]

1. Open file light ace detects greatly
2. Observe crash

This seems to be because the file contains valid image information with regions, we should first fix the crash:

diff --git a/view/sharedcache/core/MachO.cpp b/view/sharedcache/core/MachO.cpp
--- a/view/sharedcache/core/MachO.cpp
+++ b/view/sharedcache/core/MachO.cpp

 		}
 	}
-	catch (ReadException&)
+	catch (std::exception&)
 	{
 		LogError("Export trie is malformed. Could not load Exported symbol names.");

Then possibly have a fast-fail for when regions are missing for images.
