glibc detected *** sudo: free(): invalid pointer: 0xb7ce3b28

[patrice]

Ubuntu version: Hardy Alpha 4

This problem occured on march 13th during a apt-get update using the package managing tool in taskbar.

Last successful apt-get update: march 12th

Packages seem to have been downloaded, but I cannot confirm. When I looked back at the window, a popup window said there was an error. And now, using "sudo apt-get ANYTHING" gives the following:

patrice@evo:~$ sudo apt-get check
