It looks like the web process is crashing? Do you have web process crash logs?

Comment 3 2012-09-13 04:13:07 PDT
The issue seems to be that WebPage::updatePreferences is called in the WebPage constructor (in WebPage.cpp:310) before the drawing area is created (in WebPage.cpp:318), therefore after r128245 settings->setForceCompositingMode is never called since m_drawingArea is not yet initialized when WebPage::updatePreferences would call m_drawingArea->updatePreferences(store).

Comment on attachment 163840 [details] Patch Looking at platform implementations this doesn't seem to be an issue yet, but I'm wondering if we shouldn't make sure that platformInitialize() keeps being run after updatePreferences. Tell me what you think, this can be moved once it's needed too.

Indeed, it could be safer for future implementations of platformInitialize() that might want to set custom settings.
