I have the same issue.

It appears that from r5805 to r5806 the ”group“ and ”other” 
permissions in the MailMate.app folder were changed from ”r-x” to 
”——”, so executing for anybody but the owner is not possible 
anymore (as is the case when installing the application from an 
administrator account, and then trying to use it from any other 
account):

➜ ls -al MailMate_r5805/MailMate.app/
total 0
drwxr-xr-x@ 10 michael  staff   320B May 13 22:05 Contents
➜ ls -al MailMate_r5806/MailMate.app/
total 0
drwx------@ 10 michael  staff   320B May 17 21:31 Contents

The same holds for the hierarchy below ”Contents” (and for r5807).
