test-giza-xw sometimes fails

[olebole]

Hi,

I just got a bug report Debian#1101626 about a failing test-giza-xw test:

I could reproduce this only in one of 10 times, so it seems rare. For the Debian package, I just disabled the test.

I had a quick look but nothing obvious here, disablement is ok for now
