Application: akonadi_imap_resource (5.13.0 (19.12.0))

Qt Version: 5.14.0
Frameworks Version: 5.65.0
Operating System: Linux 5.4.8-arch1-1 x86_64
Distribution: Arch Linux

-- Information about the crash:
Since last big update (19.12) one of my email accounts using IMAP crashes arbitrarely (or that's what it looks to me).  It only happens to one in particular, the rest still function perfectly. I am using Archlinux, but I have compiled with debug symbols some of the involved packages (kdepim-runtime, akonadi...).

The crash can be reproduced sometimes.

-- Backtrace:
Application: me@iyanmv.com (akonadi_imap_resource), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
