Error in setting SMPlayer as default application

I am trying to change the default app from Totem to a SMPlayer with a newly installed Ubuntu 11.10 but an error appears stating "SMPlayer" as default application: Can't create user application configuration folder /home/manu/.local/share/applications: Not a directory".
This is a application for my AVI files. Please help me resolve it.
Thanks in advance.

Could not set as default
