How does this relate to #72784?  Am I right in thinking it's a duplicate?

Either way, I'm experiencing the same problem (have checked, and the 
last few lines of my build log are the same as yours).

As a workaround until it's fixed, I've found icedove-minimal installs 
OK, and seems surprisingly full-featured for something with "minimal" in 
the name, although it took a bit of hackery to get it to recognise my 
pre-existing profile directory.
