When reviewing low quality posts, I came about the following link-only-answer, that was recommended for deletion in this [thread](https://stackoverflow.com/questions/22822743/dart-touchevent-supported-during-emulation):

The author argued in the comments, that he thinks it is better to at least have a link-only-answer than no answer at all for a question. And if I understand the SO system correctly, he is perhaps right. Here is my reasoning:

1. If this is really a known bug, then it doesn't make much sense to provide a more detailed answer. Finding and linking to the bug report is then most likely the best information one can provide for both the OP and for possible followers with the same problem.
2. If he posts this information as a comment, then the question would stay *unanswered*. If I'm not mistaken, then this would prevent possible duplicate questions from being flagged as a duplicate of this question, because the linked duplicates must always have at least one up-voted answer.
3. Finding a corresponding bug report does sometimes take quite some time, and the link to the report is in my opinion unique enough to allow a link only answer in this case.

So I would personally decide for not deleting the answer in such a case. 
What do others here think about that? Am I missing something?

Note also, that I'm talking about valid bug-report-answers in general. I didn't yet verify, if the linked bug report is actually answering the question, and it if doesn't, then of course the answer should be deleted.
