Description clx 2017-07-31 16:28:45 UTC 
Application: kmail (5.5.1)

Qt Version: 5.7.1
Frameworks Version: 5.36.0
Operating System: Linux 4.11.11-300.fc26.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed: Reply to certain emails from gmail (but not others). Simply clicking "reply" inside my gmail inbox will trigger the crash, though only when reply to certain senders, particularly those with *google.com domains. Reply to many other senders seem to be okay.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
