I can confirm this bug.
Here is a simpler way reproduce it with both the 32 and 64-bit builds of Wine:

$ mkdir "~/.wine/drive_c/one space"
$ echo Works >"~/.wine/drive_c/one space/file.txt"
$ ./wine start "c:\\one space\\file.txt"

-> This opens the file in notepad and you should see "Works".

$ mkdir "~/.wine/drive_c/one"
$ ./wine start "c:\\one space\\file.txt"

-> Now you get explorer.exe browsing the "One" directory. This is clearly not
what you want and this is caused by this bug.

A WINEDEBUG=+exec shows:

trace:exec:SHELL_execute mask=0x00008500 hwnd=(nil) verb=L"open" file=L"C:\\One
Space\\File.txt" parm=L"" dir=(null) show=0x00000001 class=not used
fixme:exec:SHELL_execute flags ignored: 0x00000100
trace:exec:ShellExecute_FromContextMenu L"C:\\One Space\\File.txt"
trace:exec:ShellExecute_GetClassKey ext = L".txt"
trace:exec:ShellExecute_GetClassKey class = L"txtfile"
trace:exec:SHELL_execute execute:L"C:\\One Space\\File.txt",L"",L""
trace:exec:SHELL_ExecuteW Execute L"C:\\One Space\\File.txt" from directory L""
trace:exec:SHELL_ExecuteW returning 5
trace:exec:SHELL_FindExecutable L"C:\\One"
trace:exec:SHELL_FindExecutable SearchPathW returned non-zero
trace:exec:SHELL_FindExecutable returning L""
trace:exec:SHELL_FindExecutable L"explorer"
