Description Jason Franklin 2019-08-12 13:20:07 UTC
Application: kmail (5.9.3)

Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.19.0-5-amd64 x86_64
Distribution: Debian GNU/Linux 10 (buster)

-- Information about the crash:
- What I was doing when the application crashed:

My KMail set up connects to a Gmail account, and I was just checking my mail.  I switched folders
a couple of times as usual.

- Unusual behavior I noticed:

I saw a multi-colored message that read "KMail is retreiving messages" or something to that effect.
Then, it just sat there and did nothing.

I then went to File > Quit to stop the application, and the crash report was generated.

- Custom settings of the application:

I use encrypted/signed mail for most of my communication. I also have a local mail folder that stores most
mail when it's been archived or deleted.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Reported using DrKonqi

Created attachment 122084 [details]
New crash information added by DrKonqi

kmail (5.9.3) using Qt 5.11.3

- What I was doing when the application crashed:

This is the same as my earlier report.  I was reading email from my linked Gmail account, and KMail
stopped in the middle of retreiving messages.

- Unusual behavior I noticed:

KMail showed a message that it was retreiving messages and then did nothing.  With File >Quit
KMail generated a crash report.

- Custom settings of the application:

Encrypted/signed email for most communication and a local mail setup that stores most of my
deleted/archived email.
