Bug 335867

Application: rekonq (2.4.2)
KDE Platform Version: 4.13.0
Qt Version: 4.8.6
Operating System: Linux 3.13.0-29-generic x86_64
Distribution: Ubuntu 14.04 LTS

-- Information about the crash:
This is very simple.. When I log into my account on www.mail.com using rekong it intermittently crashes. 

No issues with other browsers.

I don't know what else I can add here

Sam

The crash can be reproduced sometimes.

-- Backtrace:
Application: rekonq (rekonq), signal: Segmentation fault
