I'm pretty sure that the cause of the crash is that the StyledElement pointer is stale as well because I was able to reproduce the crash couple of times even with all pointers to CSS objects being RefPtrs but with raw Element pointer in InspectorStyleSheetForInlineStyle::m_element. Anyways incorrect behavior of CSS inspector is a less severe issue than non-deterministic crashes of all inspector tests. You will be able to roll out this patch locally if you want to use the crashes to spot the real problem in the code. 326652 11 yurys 2010-12-24 09:51:54 -0800 Committed r74637:
