First time the mail was quite complex - I tried several times and I can still reproduce the bug when I have virtually no data typed into the mail - just a "To:" and a "Subject: ", a non-standard choice of submitter and the pulled-in related .signature. The fault reproduces consistently. 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".
