Indeed it appears I might be:

0000000001f0de70 kdeinit4: ksmserver [kdeinit]
000000000370a088 /usr/bin/kactivitymanagerd

00007f0e54001a00 /usr/bin/pidgin
00007ffe00000001 /usr/bin/kmix

Those akonadi_agent* and pidgin ones do indeed look like addresses.

I've got nvidia-kernel-dkms 331.20-2 (from experimental), which is one
of the affected versions, apparently.

Interestingly, though, on one of the affected xterms, the mask is:

anthony@Zia:~$ grep SigBlk /proc/3289/status 
SigBlk: 0000000000000001

so that seems to be sane... except for HUP being ignored. Its parent
kdeinit4: kded4 [kdeinit] has the same.

So I'm unsure if this is really bug 728743 or not :-(
