Comment:

 This error seems to be caused by a missing cleanup in ByteSink.cpp:246
 in MgByteSink::ToFile(CREFSTRING filename)
 In this method a huge buffer (1MB) is allocated to export the byteSource
 into the given filename.
 This is the first place when a system with exhausted memory resources
 fails.
 The buffer is on the stack so thats not the problem, but
 when an exception is triggered we are left with an empty file.
 Thus a MgInvalidStreamHeaderException on the client side

 This seems to be related to ticket #520.
