Re: inserting CD-ROM crashes parted 1.6.6

Andrew,

I re-compiled parted, adding -g to CFLAGS, made sure --enable-mtrace and 
--enable-debug were passed to configure, and then ran inside gdb.

Here is the output from gdb:

This GDB was configured as "i686-pc-linux-gnu"...
(gdb) run

Program received signal SIGFPE, Arithmetic exception.

It seems that libparted/linux.c has a divide by zero at line 411; but I have 
no idea why that should be.
