Bug ID: 48061
           Summary: WineTest: get_subtests() fails randomly
           Product: Wine
           Version: unspecified
          Hardware: x86
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: testcases
          Assignee: [e-mail]
          Reporter: [e-mail]

Sometimes the DLL version section contains lines like:

mfplat=load error 1359
shell32=load error 1359
user32=load error 1359

See
https://test.winehq.org/data/6f2ef158b78f7d0a950c9398c26278d6523c112e/win10_...

This happens on all VMs. 1359 is ERROR_INTERNAL_ERROR which get_subtests()
returns when it fails to parse the test list. But it could also come from
GetLastError() though that seems somewhat unlikely.

In some cases this may make sense. For instance I assume that mfplat.dll is not
available on Windows XP so it could make sense to have this error there, though
one would rather expect a 'missing' error.

But this error happened to shell32 and user32 on Windows 10 as in the example
above!!!

This impacts the WineTest results which then impacts the ability of the TestBot
to detect new failures. So this needs to be investigated.
