Comment 5 for bug 339202

I use it every day since I posted this.

Versions:
ck: 0.3.0
g-p-m: 2.26.1
kernel: 2.6.29
do: 0.8.1.3 + the above patches

I do not use ubuntu though and from what I've seen there are various ways to use ck ( system daemon, user daemon, pam etc). But any of them seem unlikely to cause lockups.
When I get the time I can test it on Fedora (VM) and see what happens...
