Crikey, that's a dramatic solution!
strace is certainly available for FC7: yum install strace
Did you mention it was on Fedora before? If I'd noticed
I would have suggested you check the selinux log.
selinux failures also put up a warning on the gui (you
might need particular rpms installed)
Ma
I've dodged it all and installed Etch.
strace wasn't in my FC7 but it is in Etch. strace'ing on xmms
in FC7
resulted in a steady stream of data - 2 or 3 lines a second - it
would
have to be carefully grepped to see anything useful.
