Comment 62 for bug 870326

it seems to be the Software Center (SC) that triggers this behavior.

i have run the following snipet multiple times - checking to see if it was related to size of files would cause it.
for i in {1..100} ; do dd if=/dev/urandom of=file_n_$i.dd bs=${i}M count=1 ; done

nothing happens

but following Richard Perdal's comment, i left the above snipet running and opened SC - and the errors started again.

my installation is 11.10 amd64 using Intel i5 with nvidia gpu
my partitions:
<root> is btrfs
<home> is EXT4

would like me to gather further info?
