*** Bug 1472977 has been marked as a duplicate of this bug. ***

I cannot reproduce your backtrace.
Are you still able to reproduce your backtrace?

Your ibus-x11 failed in calling exit(EXIT_FAILURE).
Googling that failure of __run_exit_handlers(), seems a buffer overflow might happen so the backtrace itself does not help to resolve your problem and need to know the reproducing steps exactly to reproduce your problem.

I posted the backtrace after noticing the corresponding alert in the "Problem Reporting" utility. I have no memory of the precise circumstances of this crash. Nevertheless, the issue is current and real.

So are you still reproduce your backtrace?

(In reply to fujiwara from comment #16)
I do not know the precise circumstances which triggered this crash so I am unable to reproduce it deliberately.

How many times can you reproduce your backtrace per day?
I mean if you can reproduce your problem frequently, I will ask some debug tests to try to get the root cause. But if you cannot, I have no way to investigate your problem and also think this is not so important issue.

(In reply to fujiwara from comment #18)
This crash occurred only two days ago, and I have not seen it again yet. I would therefore say: "wait and see". If it was a random crash, this bug report will be closed anyway when Fedora 26 reaches end of life, thanks.

We are working on F26 bug triaging activity, basically to make sure important bugs will not get closed automatically and those might get reproduced in next release.

From above comments it looks like we are not able to reproduced this issue. Closing it as of now, if you still feel this is an issue, feel free to reopen. 

Thanks.
