[imp] warnings after configuring

[Eduardo Del Valle Flores-Guerra]

This is the third time I install horde+imp, and the first time I've seen this 
problem. Everithing done by the book, still unable to solve it.
Any clue?

This are the msgs that appear after I login (succesfully)...
then I'm able to see my inbox, but as soon I click on something I logs me out.

Thanks in advance.
