Since upgrading from 433 to 434 I'm seeing a crash when calling send() from the corex module The backtrace is included below

It looks like the problem was introduced in 027495fb (cherry picked into 43: 4fdd1169, 42: 5b93cc21 and 41: 8e010d9f)

I can confirm that 434 with 4fdd1169 reverted doesn't crash
