I would definitely do it if I had /var/tmp/kde4* or ~/tmp/kde4*. *But* I do
not.

{pts/0}% ll -d ~/tmp/k*
drwx------ 21 bor bor 24432 2008-05-12 20:33 /home/bor/tmp/kde-bor/
drwx------ 2 bor bor 4496 2008-05-12 20:33 /home/bor/tmp/ksocket-bor/
{pts/0}% ll -d /var/tmp/kde*
drwx------ 7 bor bor 296 2008-05-11 20:15 /var/tmp/kdecache-bor/
drwx------ 2 root root 48 2008-04-26 09:01 /var/tmp/kdecache-root/
drwx------ 4 test test 216 2008-05-11 21:05 /var/tmp/kdecache-test/

which implies that those directories are shared between KDE3 and KDE4; and
this means that it is not safe to run KDE3 and KDE4 side by side.

This may also account for a plasma crash. I will remove them and test again.
