Comment 1 Kai Krakow 2016-06-30 22:03:23 UTC 
This crash occurs every time I select one specific mail.
Comment 2 Justin Zobel 2020-12-17 05:27:42 UTC 
Thank you for the crash report.

As it has been a while since this was reported, can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved.

I have set the bug status to "needsinfo" pending your response, please change back to "reported" or "resolved/worksforme" when you respond, thank you.
Comment 3 Kai Krakow 2020-12-17 14:23:21 UTC 
I'm no longer using kmail due to its instability, potential to eat my mails, bad impact on system performance, and it being unusable on HiDPI monitors. I may try again sometime in the future but currently I'm going with using Mailspring and web mailers.
