Comment 4 for bug 437180

This is also happening to me. But it is not belongs only to Pidgin but Empathy too. I do not have have these contacts blocked. Actually if they contact me the window chat pop ups but still they are not listed in the contact list. Besides if I go to the yahoo mail internall messenger those contacts appears.
I had this problem originally with 10.10 and now with 11.04, always in 32 bits.
