Bug ID: 52172
           Summary: Guild Wars 2 spams
                    "0150:fixme:msctf:KeystrokeMgr_TestKey{Up,Down} STUB"
           Product: Wine
           Version: 6.23
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: msctf
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

When playing Guild Wars 2, for every key press these two fixmes get printed:
0150:fixme:msctf:KeystrokeMgr_TestKeyDown STUB:(00000000022C5840)
0150:fixme:msctf:KeystrokeMgr_TestKeyUp STUB:(00000000022C5840)

While walking (with WASD) the KeyDown one gets printed continuously, which is
especially annoying.

Best I can tell there's no related problem, so just silencing these messages
would work for me.
