RevMail crashing in iOS stack - LC 6.6 - 7.0.1

I am having a problem getting RevMail to work in an IOS LC stack. I have 
tried five different versions of LC (from 6.6 to 7.0.1), but each time I 
try the RevMail function, the system displays a blank email with only 
the subject line filled in. I can't get the email address or body to 
fill in. The blank email sits there for about 10 seconds, then I get a 
crash report (part of which is shown below).

Yosemite 10.10.2
Xcode  6.6.1

Not sure which version of the iOS SDK is installed (how would I identify 
that?), but I thought the latest version was installed when I installed 

The stack I am testing has only one card and one button, with this script:

on mouseUp
    revmail "wow at",,"Help","data"
end mouseUp

Any ideas?
