Comment 10 for bug 438463

I have a similar (more or less identical, actually) problem on Debian/sid (with many different combinations of webkit and epiphany, including several git revisions). Specifically removing session-crashed.xml works around it (this is undesirable in many cases though). Reproduceable on both ATi Catalyst and the free drivers.

Interesting thing about this one, breaking on gdk_x_error is ineffective (with or without --sync command line). Don't know if that's something peculiar at my end or not.
