Sentry Crash Report:

Description blinkey 2020-01-13 20:38:58 UTC 
Application: kmail (5.7.3)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-74-generic x86_64
Distribution: Ubuntu 18.04.3 LTS

-- Information about the crash:
- What I was doing when the application crashed:
using IMAP the folders for "Fastwebnet.it" where displayed, but any msg selected  was not displayed, 
Kmail goes into an endless wait state for recalling folders contents.
So i choose to close Kmail, and got the windows "segmentation fault"
Another try shows that 
1. local msg and other Imap are displayed as usual
2. only "Fastwebnet.it" folders does not work,  goes in wait state and displays no msgs anymore 
Can be a bug of Fastwebnet.it, but why Kmail locks itself so bad ?

The crash can be reproduced every time.

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