It is P1/critical bug, because it is a crash. 507959 2 ossy 2011-11-22 23:33:40 -0800 Pavel, have you got any idea how http://trac.webkit.org/changeset/100926 broke this test? Unfortunately we don't have gdb backtrace in debug mode, because debug linking is impossible nowadays on 32 bit. (Linker runs out of 4Gb address space) 507963 3 ossy 2011-11-22 23:52:40 -0800 We can easily reproduce it with the following command: $ Tools/Scripts/old-run-webkit-tests inspector/extensions/extensions-console.html inspector/extensions/extensions-events.html 509148 4 pfeldman 2011-11-25 06:35:36 -0800 I was recently making inspector tests on Qt pass. 555195 5 ossy 2012-02-13 05:08:45 -0800 It works now, so I unskipped it - http://trac.webkit.org/changeset/107560.
