-- Information about the crash:
I was working on Drupal administration tasks, and when clicking some button the browser crashed. This has happened before when clicking some other link or button, but happens inconsistently (the same button usually works, but then suddenly crashes).

The crash can be reproduced some of the time.

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