Comment 15 for bug 275218

Version: 1.10.0 (using KDE 4.1.0)
Installed from: Ubuntu Packages
OS: Linux

When I try to compose an new message with kmail (either embedded in kontact or in stand alone), the application freeze and kmail get 100% of CPU.

Here is a backtrace of kmail when I get this hang (no crash) :
