Polkit General Protection Fault

[Arthur Dent]

Hello All,

I have, for some time, been getting these messages in my logs:

=============8<=============================================
WARNING:  General Protection Faults in these executables

Should I be concerned? (and what, if anything, should I do about it?)

I am not aware of any undue problems, but it's a scary looking error message...

Thanks in advance...
