nsILocalFile is an XPCOM interface.  Please ask this question
in the xpcom newsgroup/mailing list.  You can find it by
searching for "xpcom" in this page:
http://www.mozilla.org/community/developer-forums.html

The Unix/Linux implementation of GetDiskSpaceAvailable is here:
http://lxr.mozilla.org/seamonkey/source/xpcom/io/nsLocalFileUnix.cpp#1144

Since Linux has both <sys/statfs.h> and <sys/statvfs.h>, it seems
that this method is implemented.  I suspect that the call failed.
Check the return value of mFile->GetDiskSpaceAvailable(&iSize).
Does it return NS_ERROR_FAILURE or NS_OK?  If it returns
NS_ERROR_FAILURE, what's the value of 'errno'?
