I'm sure I've seen this in a ruby tool ( maybe @KrauseFx's fastlane? ) but taking the 2.3.0 issue as an example:

What if we took the first 3 or 4 words from the error and searched for issues for that: so taking this issue #4748

Crashing line: NoMethodError - undefined method 'to_ary' for #<Pod::Specification name="iVersion">'
Assuming the NoMethodError is already a separate token of the error if we just did a search for undefined method to_ary:

https://github.com/CocoaPods/CocoaPods/search?q=undefined+method+%60to_ary%27&type=Issues&utf8=✓ this gives us 12 results

We could probably reduce a lot of issue churn by having it automatically search like this in the exception.
