Created attachment 119697 [details] The command line output observed during new mail crash. SUMMARY Kmail crashes when creating a new mail. STEPS TO REPRODUCE Not sure how to reproduce, but I see the issues on two similar KDE neon installations, so I am wondering why nobody else seems to have reported it. The history of the crash is as follows. I experienced a crash of kmail (for whatever reason; In one case I modified the plugin settings trying to enable language tool grammar check). After the crash kmail did not start anymore (crashing each time at start). I figured that I could fix that with rm -r /home/andreas/.local/share/kmail2/autosave After that kmail can be started again without immediate crash. However, clicking the new mail icon (or pressing a shortcut that would also bring up a new composer window) crashes kmail with the trace below. In the second attachment I provide the trace that I get if I do not remove the autosave directory, in which case kmail crashes right at the start. OBSERVED RESULT Kmail crashes leaving the attached output on the command line. The consequence is that it cannot be used anymore to write and send mail. EXPECTED RESULT Kmail shows a new composer window.

Created attachment 119698 [details] Debug trace of kmail for crash during startup (observed when not deleting autosave folder)
I should have mentioned that, in order to exclude inconsistent settings as cause of the crashes, I deleted all kmail/kmail2 relevant settings I have been able to identify in my home directory, except for the akonadi account settings. This does not change the observed result in any way.

This does not change the observed result in any way. Still, please check whether the "Share Text" plugin is enabled in kmail's plugins settings. (it should be disabled by default, but maybe you missed some config file) Your backtrace does look very similar to the one from bug#403317.
No response; assume it is a duplicate. If you can still reproduce with KMail 5.11.1 from KDE Applications 19.04.1, please add a comment or reopen the ticket. *** This bug has been marked as a duplicate of bug 403317 ***
