android apk in mime.types

[itpp2012]

Firefox/IE sometimes gets an android apk as text, this forces octet, anyone
see any issues?

conf/mime.types
line 64:
    application/octet-stream              iso img;
-    application/octet-stream              msi msp msm;
+   application/octet-stream              apk msi msp msm;
