What steps will reproduce the problem?
1.
create a unit test with a setUp() which throws an exception
like calling a method on null
2.
run the test
3.
Output

processMessage(): unittest-suite-wait-for-done
processMessage(): unittest-suite-done
Calling notifyDone()

What is the expected output? What do you see instead?
stack trace is printed

What version of the product are you using? On what operating system?
Dart VM version: 1.1.0-dev.5.4 (Wed Jan 8 09:32:13 2014) on "linux_x64"

Please provide any additional information below.
When I enclose the code in setUp in try/catch I get the actual exception in the catch block.
