Componenets installed by winetricks have "deadbeef.manifest" trailer in their manifests, so it's not clear that filtering logic works. On the other hand when manifests for versions 1.2.3.4 and 1.2.3.10 are installed and application exe needs version 1.2.0.0 and later uses LoadLibrary() to load a plugin.dll that needs 1.2.3.7, version 1.2.3.4 gets loaded with an .exe (because manifest for version 1.2.3.10 is ignored) and version 1.2.3.10 gets loaded with a plugin.dll, and this leads to crashes.

This patch fixes the case when an application installed manifest and one installed with winetricks differ in build/revision fields, however due to a bug (that the patch fixes) both get loaded (one by main exe, another one by a plugin) and this leads to a crash in plugin dll because some initialization APIs are not called in the 2nd case.
Is there nything else that needs a clarification?
I'm not sure I understand what winetricks is doing here with builtin manifests, but in any case the filtering was added for a reason. The algorithm may need to be made smarter, but simply removing it is going to reintroduce the problem that this was addressing.

It's not about builtin manifests. It's about mfc90.dll. 'winetricks -q vcrun2008' installs mfc90.dll version 9.0.30729.6161, and the application ships with 9.0.30729.1. In both cases manifest file names end with deadbeef.manifest, and being removed code treats these manifests as builtin, which is wrong.

It looks like the real issue is that the assembly cache is installing native manifests with deadbeef names.
