A week or so ago I forked and got the backtrace with links to open source files in an editor working under Rails3.
This required a bit of monkey-patching to Rails::BacktraceCleaner to allow replacing some of its filters.
It might not be the cleanest solution but it appears to work.
I then noticed that the gem had been changed to remove the backtrace function. I merged and restored it in this commit.
What do you think?
fix backtrace for rails 3
