http://trac.webkit.org/changeset/121058 broke the build:
Patch causes plugins tests to crash in GTK debug builds (Requested by zdobersek on #webkit).

This is an automatic bug report generated by the sheriff-bot. If this bug
report was created because of a flaky test, please file a bug for the flaky
test (if we don't already have one on file) and dup this bug against that bug
so that we can track how often these flaky tests case pain.
