Bug ID: 36168
           Summary: shell32/shlfolder test fails if current directory has
                    directories named 'a' 'b' or 'c'
           Product: Wine
           Version: 1.7.17
          Hardware: x86
                OS: Linux
            Status: NEW
          Keywords: download, source, testcase
          Severity: major
          Priority: P2
         Component: shell32
          Assignee: [e-mail]

I noticed that shell32/shlfolder failed on one my machines:
shlfolder.c:2813: Test failed: ParseDisplayName returned 80070002
shlfolder.c:2813: Test failed: ParseDisplayName returned 80070002
shlfolder.c:2813: Test failed: ParseDisplayName returned 80070002
shlfolder.c:2813: Test failed: ParseDisplayName returned 80070002
shlfolder.c:2813: Test failed: ParseDisplayName returned 80070002
shlfolder.c:2813: Test failed: ParseDisplayName returned 80070002

looking at the code, I noticed it was using directories named a,b,c in the
current directory. If those directories exist and are not writable (e.g., a
mounted iso), the tests will fail.

The tests should be using a temporary directory instead (and checking that the
directory isn't already present).
