>Description:
	Trying to create a new file when there are zero bytes free in the
filesystem leads to the SIGSEGV. Backtrace is:

#0  0x40859212 in chunk_alloc (ar_ptr=0x4090a480, nb=368) at malloc.c:2878
#1  0x40858fff in __libc_malloc (bytes=364) at malloc.c:2810
#2  0x4084aa9d in _IO_new_fopen (
    filename=0x82b3afc "/home/rap/.audacity_temp/b00040.auf", 
    mode=0x8151004 "w+b") at iofopen.c:50


>How-To-Repeat:
	Simply try to create a file with zero free bytes on the fs.

>Fix:
	None discovered 8-(
