            Bug ID: 225921
           Summary: [GTK] Several printting/ related tests are crashing
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: New Bugs
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: dpino at igalia.com

There are three printing tests that have been constantly crashing for a long time. This crash was hiding because the tests were marked as flaky. The tests are:

  editing/execCommand/print.html
  fast/media/print-restores-previous-mediatype.html
  printing/print-close-crash.html

Results dashboard:

https://results.webkit.org/?suite=layout-tests&suite=layout-tests&suite=layout-tests&test=editing%2FexecCommand%2Fprint.html&test=fast%2Fmedia%2Fprint-restores-previous-mediatype.html&test=printing%2Fprint-close-crash.html&platform=GTK&platform=WPE

All tests share the same stacktrace. There's a debug stacktrace for fast/media/print-restores-previous-mediatype.html which I past below:

Program terminated with signal SIGTRAP, Trace/breakpoint trap.
