Description Ivan Tonchev 2011-07-18 19:55:25 UTC

Version:           4.4.10 (using KDE 4.6.2) 
OS:                Linux

Hello everyone,

After i enabled HTML formating in Kmail composer replying to long messages has become a headache. Kmail hangs, interface is completely frozen, during which time CPU usage is high. After a period of time (depending on how long the message to which i reply is) the program recovers for a few seconds and i can type a few words then in hangs again and the cycle goes on. 

Reproducible: Always

Steps to Reproduce:
1. Enable HTML formating in Kmail's composer.
2. Exchange several emails by replying (keep quoting the original messages). Do it until the email becomes several hundred lines long.
3. As the email grows longer the responsiveness of Kmail will decrease until it becomes unusable. 


Actual Results:  
Kmail becomes unusable - frozen interface for both composer and main KMail window.

Expected Results:  
To let me type the message.

Never happened when i was writing plain text messages

I upgraded KDE to 4.6.5 but Kontact is still 4.4.10. Which version of KDE comes with Kontact 4.6.1?

I can confirm that this bug is still existent in kmail 15.12.1-1. It is really frustrating. If anyone needs some more info, please let me know.
