We need to know why the SourceDir property is not set here, so please attach a +msi trace that includes a proper backtrace with line numbers.
I am not sure why +msi or the winedebugger dump didn't show line numbers - I did compile with -g.
Is it not possible for the msi not to set the SourceDir property? The crash is 100% sure at lstrcpyW() copying NULL.
