Application: rekonq (2.3.2)

-- Information about the crash:
- What I was doing when the application crashed:

While navigating a forum thread (links below), rekonq crashes with a segmentation fault. The links in question are the hyperlinks labeled "1" and "2" at the bottom of the pages, which take you to page 1, or page 2, respectively.

http://us.generation-nt.com/answer/gentoo-user-emerge-problems-help-210729502.html?page=2

The crash happens 100% reliably when navigating to one of the pages from the other, even if that navigation does not actually involve clicking a link, i.e., pasting the URL into the URL bar. It happens much less reliably, but often, when navigating away from one of the given URLs to any other arbitrary URL.

The crash can be reproduced every time.
