Can someone help me in identifying the source of this crash that I see in crash logs?

Please post a full crash report. For hints and tips on how to do this, see Posting a Crash Report.

Here is the full crash report. I think earlier it failed to upload the full report as the file was in rtf format (possibly).

Much better. Thanks!

I ran your report through an internal tool and it shows that a similar crash has happened with other apps, but it’s really rare. How reproducible is in your case?

Also, thread 6 of your report shows evidence of a third-party crash reporter. While there’s no evidence that this has messed up this specific crash report, my experience is that third-party crash reporters are not to be trusted [1]. I recommend that you disable this and, if the crash crops up again, you’ll have a ‘clean’ crash report.
