113948 - nsContentDLF::CreateInstanceForDocument() is called before gUAStyleSheet has been loaded

Status: RESOLVED FIXED

(Core :: Layout, defect)

Description

[Simon Fraser [no longer active]]

I'm seeing a warning in my current build:

WARNING: unable to load UA style sheet, file nsDocumentViewer.cpp, line 3952

It seems that nsDocShell::CreateAboutBlankContentViewer() is calling 
nsContentDLF::CreateInstanceForDocument() before nsContentDLF::CreateInstance() 
is every called (which is where we load the UA stylesheet, so gUAStyleSheet is 
null at this point. So we set a null UA stylesheet on the document viewer, which 
then asserts in DocumentViewerImpl::CreateStyleSet().

Both nsContentDLF::CreateInstance and nsContentDLF::CreateInstanceForDocument
now call EnsureUAStyleSheet (as a result of fixing bug 115919).  So this should
be a non-issue....

This bug is targeted at a Mac classic platform/OS, which is no longer supported
by mozilla.org. Please re-target it to another platform/OS if this bug applies
there as well or resolve this bug.

I will resolve this bug as WONTFIX in four weeks if no action has been taken.
