Failing unit test in Mac OS X Yosemite 10.10.1

Hi everybody,

As I had mentioned in another thread, a unit test has been failing in my
machine for some time. This is not a fatal error, but I think it would be
beneficial to understand where the problem comes from.

The test is CppunitTest_sw_ooxmlexport (ooxmlimport failed for some time,
but apparently got fixed). It fails on the following condition:

Test name: testCropPixel::Import_Export_Import
assertion failed
- Expression: getXPath(pXmlDoc, "//a:srcRect", "l").toInt32() <= 21856

Failures !!!

Error: a unit test failed, please do one of:

export DEBUGCPPUNIT=TRUE            # for exception catching
export CPPUNITTRACE="lldb --" # for interactive debugging on OSX
export VALGRIND=memcheck            # for memory checking

and retry using: make CppunitTest_sw_ooxmlexport

    ...at least, that's the value for me on Mac with retina

My Mac (Retina 13") gives the value 22452, but I'm not able to tell which
value is "valid", or on which Mac with retina the other value was produced.
Does anybody else use OS X Yosemite here?

Thanks,
Renato.
