QLocale::system().name() returns "C" instead of "de"

[momesana]

Hi, I am working on a german windows 2000 workstation and wanted to try out a little application that I have written for our company. I had created translation files and wanted to load them at startup but realised they were not loaded. After putting in debug print statements I found out that the locale returned is "C" -- the fallback default locale -- as opposed to "de" which should be the case since this is a german windows installation. Can anybody tell me what I am doing wrong? May it be a windows 2000 issue?
