Bug 45525 – REGRESSION(r67176): editing/selection/doubleclick-inline-first-last-contenteditable.html crashes

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Ryosuke Niwa]

After r67176, editing/selection/doubleclick-inline-first-last-contenteditable.html constantly crashes on Qt Linux Release.
Since the code modified in r67176 is never executed in the test, the cause of the crash is not the changeset 67176.

Thank for reporting and skipping the test.
But it shouldn't be closed until the real bug fixed.

Let's see the backtrace for crash.

Oops, that wasn't intended.  It seems like webkit-patch did that because I included the bug number in the changelog.

Why is it calling copy?  That doesn't make any sense.  The test only tests selecting text by double-clicking and click + modify selection.  This must be a qt-specific behavior because on Mac, it's never copied.

[Ryosuke Niwa]

Ah! this crash is reproducible on Mac as well.  Will submit a patch shortly.

Great, I tested editing/selection/doubleclick-inline-first-last-contenteditable.html and the new test, and both of them pass.

Thanks for testing my patch!
