Package: dbus-broker
Version: 37-3
Severity: important
Hi,
This seems to be a strlen() on a NULL-pointer...
To reporoduce (hopefully):
1. Insert drive with LUKS-encrypted data (I use no partition table on my
drives, not sure if relevant)
2. Click the mount button on the Drives Plasmoid
3. Enter passphrase
4. Click ok
5. dbus-broker crashes and pulls other dbus-connected applications with
it
6. Despair in front of your unusable desktop (Logout/reboot in Plasma
doesn't work anymore, probably because those are dbus actions?)
7. Desktop "disappears" some minutes later (Some watchdog kills kwin?)

I'm reluctant to provide core dump, because passphrases/secrets...
There seems to be a Debian-specific patch around the AppArmor-stuff, so
I haven't reported this upstream yet.
