Today's diary: Devel::StackTrace 1.28 has a bug
Devel::StackTrace 1.28 and 1.29 breaks Plack::Middleware::StackTrace. It's solved.
@yoshidaster tells me about Devel::StackTrace 1.28 breaks Text::Xslate's test case.
Then, I points the issue exists between Plack::Middleware::StackTrace and Devel::StackTrace.
I tell it to @miyagawa, and he send a patch to Dave. He release 1.30, was fixed the issue.
