--- Comment #3 from Yury Semikhatsky <yurys at chromium.org>  2010-12-23 07:17:00 PST ---
I was able to reproduce this crash by simply running DumpRenderTree on Qt Linux Debug with the following command line(note that the test is different):

gdb --args WebKitBuild/Debug/bin/DumpRenderTree  LayoutTests/inspector/console-command-clear.html <...> LayoutTests/inspector/console-command-clear.html

Stack dump is:

Program received signal SIGSEGV, Segmentation fault.
