Version:            (using KDE 4.3.4)
Compiler:          Gnu C 4.4 
OS:                Linux
Installed from:    Debian testing/unstable Packages

Application that crashed: kmail
Version of the application: 1.12.4
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.32 x86_64
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
KMail appears to have an instability that crops up just when the user tries repeatedly to open a web page based on the URL in an e-mail. I know that was happening to me this time, at any rate. N.B.: I cannot say whether the initial problem was in Kmail or in the browser (Opera 10.10). Thank you very much for your efforts to fix this bug! :)
