Bug 9910 – LOG ERROR: hit a RenderWidget without a corresponding Widget, means a frame is half-constructed

• Component: Frames
• Status: NEW

[David Kilzer (:ddkilzer)]

I noticed the following log error in the output of a leaks-test on the buildbot:

=================
ERROR: hit a RenderWidget without a corresponding Widget, means a frame is half-constructed
(/Users/buildbot/Desktop/BuildData/WebKit-BuildSlave/post-commit-leaks-powerpc-mac-os-x/build/WebCore/bridge/mac/FrameMac.mm:1438 passMouseDownEventToWidget)
=================

This seems to be intermittent as the next leaks-test that compiled and ran did not exhibit this behavior.  I don't think that the patch applied would cause this, either.

Thanks to Google, I found another occurrence of this in Build 2050:

http://build.webkit.org/post-commit-leaks-powerpc-mac-os-x/builds/2050/step-leak-test/0

Leaks-test build 2050 was built due to r15338, which was a ChangeLog edit (obviously not the cause).

Perhaps bdash can find other occurrences using grep?
