A strange thing: Always after I start an application which runs with root permissions (e.g. Synaptic), I get a mail titled SECURITY information for [hostname] telling me about "3 incorrect password attempts" -- though I only entered my password once (correctly) and it was accepted immediately (application started):
[hostname] : Nov 18 16:07:54 : [user] : 3 incorrect password attempts ; TTY=pts/6 ; PWD=/home/xxxx/xxxxxx ; USER=root ; COMMAND=/usr/lib/kde4/libexec/kdesu_stub -
I wouldn't mind that if there really were "3 incorrect password attempts" -- but it's annoying (and confusing) when there weren't.
Any idea what could be going wrong here?
