bootchart problem

[R Kimber]

On recently rebooting after an update,  bootchart started to use
all available memory and 100% CPU. After killing the process I used
synaptic to remove bootchart and all its configuration files.

However, rkhunter now starts to complain that it has found a new hidden
directory /dev/.bootchart. This is quite large.  One file, proc/kcore,  is
reported by ls as 140737486266368 bytes, though du can't access most files
so I don't know what the total size is.

Many files, which are owned by root, have only read permission, and
whatever I try with sudo results in an 'Operation not permitted' or a
'Permission denied' message.

How may I delete this directory? I can't see any reference to the directory
in the docs on the bootchart website.
