Thanks for the report. This error is a mistery for me, since Exception#backtrace_locations is supposed to return an array. I need to understand why the original backtrace is a string.

Could you provide me the type of the original exception please ? Is it possible that the method backtrace_locations of the original exception has been overridden ?

I honestly wish I knew what the original exception was! I throw a lot of ActiveResource::ClientError and ActiveResource::ServerError, but that's just a statistic. I was also doing work on my local machine and was connected to my production DB and that connection is always flaky, so I get a lot of ActiveRecord connection errors. But those are just guesses.

I did try to get a breakpoint into your code to debug it but wasn't successful. I did see that that method sometimes returns nil also. Seems like a truly buggy method! :(

I have added a fallback to the old way in this case and some logging. Can you try to reproduce with the following version in your Gemfile please ?

gem "rorvswild", git: "https://github.com/BaseSecrete/rorvswild.git", ref: "42b66153ad0db9d7ab849e073604cec660f4d191"

If the error happens again, something should be printed by the following command grep -A 20 'Exception#backtrace_locations' log/development.log.

Alright. I'm a bit apprehensive about running special versions of the code but for a little while I'll try it. I was able to reproduce the error twice in a row but then it stopped happening...

Do you have more details about the origin exception where backtrace_locations returns a string ?

@alexisbernard I do not and I do not know if I ever will again. If and when I do, I will surely let you know
