Bug 61937 – [GTK] Tests crashing on GTK debug bots because of failing ASSERT in webkitwebdatasource.cpp

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: Tools / Tests

[Mario Sanchez Prada]

The following tests are crashing frequently in the debug GTK bots:

  http/tests/fileapi/create-blob-url-from-data-url.html
  http/tests/history/back-during-onload-triggered-by-back.html

In all those cases (and perhaps some more that I was not able to find) the reasons seems to be the same one, a failing ASSERT in FrameView.cpp:2422:

ASSERTION FAILED: !priv->loader->isLoading()
../../Source/WebKit/gtk/webkit/webkitwebdatasource.cpp(86) : void webkit_web_data_source_dispose(GObject*)

Here you have the full backtrace:

For the time being, skipping those tests in GTK

Skipped yet another test failing for exactly the same reason:

We've skipped so many tests for this issue it'd really be a good idea to get to the bottom of it. Likely the assert is misplaced, but perhaps we can look back through the trac to find out when this started happening.
