Problems with GBufferedOutputStream

Hi!

I came across a problem with GBufferedOutputStream and
g_output_stream_write recently. If I try to write more data than the
buffer size, not everything is written to the file.

The attached example should write:
0123456894568
This is just a simple textabcdefgh


But the contents actually are:
012345684568
Thi


Am I missing something or is this a bug?
