[Bug 28288] New: msctf/inputprocessor.ok test flaky

http://bugs.winehq.org/show_bug.cgi?id=28288

Summary: msctf/inputprocessor.ok test flaky
           Product: Wine
           Version: 1.3.27
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

On all three of my build slaves, on both i686 and x86_65, 
inputprocessor.ok sometimes fails with:

../../../tools/runtest -q -P wine -M msctf.dll -T ../../.. -p msctf_test.exe.so
inputprocessor.c && touch inputprocessor.ok
fixme:msctf:TextStoreACPSink_OnLockGranted OnLockGranted called for something
other than an EditSession
inputprocessor.c:2117: Test failed: OnSetFocus expected current focus 0x12d410
got 0x12d470
inputprocessor.c:538: Test failed: Unexpected ThreadMgrEventSink_OnSetFocus
sink
inputprocessor.c:549: Test failed: Sink reports wrong previous focus

http://test.winehq.org/data/tests/msctf:inputprocessor.html 
reflects this; failures pop in and out for Linux.

Is this a window manager problem?
