Hi all,

I don't know exactly whether this is a bug or what, but I deemed it
useful to report what happened.

While running a script to backup my /usr dir to a partition on a second
HD I had to stop it with CTRL+C as the destination partition had no more
space on it.
After that I noticed I could no longer use ls (or dir) and a few other
basic progs and got instead this error:

sleep: error while loading shared libraries: libpthread.so.0: invalid
ELF header

In my wandering around for a solution I did a vim /lib/libpthread.so.0
and could see a few lines of text (instead of the unreadable symbols
which usually that command would yield). Unluckily, I didn't take note
of the text!

After a while I apparently solved the problem copying the library
libpthread-0.10.so from the backup dir into my working /lib dir; now the
ls and similar commands work, but mplayer, xine, aviplay still complain
about missing libpthread.so.0! [see below].
I reconfigured or even re-installed those applications, re-configured
libc6, but I'm still getting the same error.

An ls -l /lib shows that libpthread.so.0 points to libpthread-0.10.so,
so I don't understand what is wrong. 
The main question, however, is what might have caused this mess!

Thanks for your attention.
Regards,
	Ennio.

PS: After re-installing libc6 directly from the Debian site everything
seems to work well now :-)
