rekonq freez when trying to playback HTML5 video. That also may happen when I open new tab with HTML5 video player or close tab with HTML5 player. Anyway, after two days of testing I guess this hang most likely related to HTML5 media stuff.

Reproducible: Sometimes

Steps to Reproduce:
1. Disable loading of external plugins or uninstall Adobe Flash Plugin.
2. Browse Kickstarter, YouTube, Vimeo, watch video.
Actual Results:  
Sometimes rekonq hang. If we doesn't try to use HTML5 video playback - rekonq doesn't hang.

Expected Results:  
Newer hang.

This hang reproducible on both of 1.80 and 2.0 builds, but since I have debug symbols only for 1.80 - attached backtraces taken from build 1.80. Hope it help.

Kubuntu 13.04.

After further investigation - that was bug in glibc: http://sourceware.org/bugzilla/show_bug.cgi?id=14417 (glibc bug -> PulseAudio hang -> GStreamer hang -> rekonq hang).
