Created an attachment (id=46740)
 --> (https://bugs.webkit.org/attachment.cgi?id=46740)
iexploder test causing a crash, most likely due the ruby element.

The attached test case used to crash in the "ruby" handling of RenderBlock
(called from RubyElement) after the changes of the 15th it is still crashing
but without ruby being in the backtrace.

The backtrace is coming from Qt but it was crashing in a recent Chromium build
(PPA for Ubuntu) as well.

backtrace in a release build:
