svn commit error on XP using Qt creator

[yycking]

I can not commit svn on XP using Qt creator
But it can work very well on Mac

Executing: C:\Program Files\VisualSVN Server\bin\svn.exe status D:\paint\script.h
Executing: C:\Program Files\VisualSVN Server\bin\svn.exe commit --non-interactive --file C:/DOCUME~1/Desktop2/LOCALS~1/Temp/qt_temp.Ya3724 D:\Anvii-Paint\script.h
svn: Error resolving case of ' D:\paint\script.h'
The process terminated with exit code 1

If I try to use other function. It can work very well.
If I use command mode. It can work very well.
So I can not use commit function on Qt creator.

Tell me what happen. THX
