While Steam does not crash anymore with 1.5.10, it does not work either - all font rendering fails, unless the -no-dwrite option is specified. All places where test should be are rendered to zero width images.
This is covered by bug 31374. You should be able to disable dwrite.dll in winecfg without any additional Stream options.
