More crashes

[Hamish Rodda]

Hi,

Here are a few more issues:
1) I'm seeing tons of DeclarationBuilder::openDeclaration: Range collapsed, 
was there a regression?

And some crashes..:

This happens 44% of the way through kdevplatform + kdevelop:
ASSERT: "previousOfSameName || !m_definedMacroNames.contains(macro.name)" in 
file /opt/kde4/src/kdevelop/languages/cpp/cppduchain/environmentmanager.cpp, 
line 259

And the following two backtraces look like QUrl threading issues:
