"Issue has already been reported" is not always true

[hoosierhobbyist]

I've noticed this recently, and I can't find any related open issues (but forgive me if there is one). Sometimes while I'm developing something brand new on quantum-shell I'll run into an Uncaught TypeError and Atom will tell me that the issue has already been reported at sedabull/quantum-shell/issues and ask me if I would like to view it. This is obviously ridiculous, but not really a major issue. The reason I'm reporting it now is because I recently had a user open an issue (hoosierhobbyist/quantum-shell#17) that he believed was a repeat, but was in fact completely unrelated to the first two issues he mentioned. I understand this feature is meant to deter many people from reopening the same issue over and over, but as it stands now it may actually deter users from reporting an issue they believe is already being worked on. Let me know if there's anything I can do to help resolve this.

NOTE: was atom/atom#7475

Currently, issue equality is based on the title. If the titles are the same, then the issue is assumed to be the same. The problem is that undefined is not a function is the vaguest error message ever. In some later version of chrome this should change.

One option could be to try and match stack traces, but that may be hard with different paths. Honestly though, this probably wont change anytime soon.

Currently, issue equality is based on the title.

That didn't seem to be the case with the ./context-menu issues. Even after I edited the main issue to have exactly the same title there were still duplicates being spawned.

Were there path differences in the title?

Not in the truncated title. And it does use the truncated title in findSimilarIssues: https://github.com/atom/notifications/blob/master/lib/notification-issue.coffee#L20

There seems to be a similar thing happening on this issue: file-icons/atom#476

As can be seen there, it's already closed, and from the other comments people seem to be redirected to an issue that's actually not the same and/or irrelevant.

Just wanted to point it, if it can help to improve the behavior of the link-error-to-issue behavior.
