The problem is reproducible only on Qt Release build. The test passes without errors in debug mode. Below is the stack trace that I observe:

http://trac.webkit.org/changeset/65503 might have broken Qt Linux Release

[Yury Semikhatsky]

Reverted in r65507.

[Csaba Osztrogonác]

Most of the unskipped tests pass, only two tests still fail:
inspector/debugger-breakpoints-not-activated-on-reload.html
inspector/debugger-cyclic-ref.html

http://build.webkit.org/results/Qt%20Linux%20Release/r65504%20%2817928%29/results.html

I propose to unskip passing tests and file a new bug for two failing tests.
