Description tjbp 2013-04-26 19:57:00 UTC

I am often sent large quantities of XML pasted in an email, and when composing my reply message I am faced with frequent hangs. KMail becomes completely unresponsive, and starts to consume about 20% of my CPU time. The more XML, the longer the hangs will last. The hang seems to be triggered when I first open the composer to reply, and then again after 8 or so words I write.

I suspect this might have a connection to the greater-than signs used to indent quoted text, and something attempting to parse them is getting confused by all the greater-than signs in the XML.

Apologies if this is a duplicate or even already fixed (though I did search), since I'm aware I'm not using the latest revision.

Reproducible: Always

Steps to Reproduce:
1. Send an email with a significant amount of XML (say ~100 elements) to yourself.
2. Open a reply to that email.

Apologies for the delay - after failing to replicate this more recently I'm wondering if the problem was actually caused by a vast number of line breaks in a long email correspondence. It seems the email clients of my other contacts are duplicating line breaks from my emails exponentially and eating memory.
