Comment 9 for bug 148806

Simply doing `apt-get install kcontrol` and then `apt-get remove kcontrol` will cause the problem, anywhere between 10%-40% of the time.

for i in `seq 1 50` ; do apt-get -y -qq install kcontrol ; echo "install $i OK"; apt-get -y -qq remove kcontrol; echo "remove $i OK"; done

As others have mentioned, there's no immediately obvious pattern to which iteration will hang.
