[dev] DB.php question

[Mario Andres Yepes C]

Greetings.

Im getting an error in serveral horde applications regarding pear's DB.php 
module. The error is:

Warning: mysql_real_escape_string() expects parameter 1 to be string, object 
given in /usr/share/pear/DB/mysql.php on line 668
 
I get this eror in kronolith and Giapeto when I accessed both applications the 
first time. Then the error was gone.

Im running the cvs (as of this morning) version of all the horde 
applications.in a Mandrake 9.1 box.

I have no Idea why this error ocurs, but if someone can point me in the right 
direction maybe I can submit a patch.

Regards
Mario
