Created attachment 91690 [details] stack trace I just reported Bug #59799, but I just ran into another crash while navigating back, but this one has a completely different trace. Program received signal SIGSEGV, Segmentation fault. WebCore::DocumentWriter::endIfNotLoadingMainResource (this=0x7fff80d81870) at ../Source/WebCore/loader/DocumentWriter.cpp:212 full trace attached (again, in thread 1).
This is a pretty old bug that I haven't seen. Please reopen if it's still an issue.
