how to disable certain xmpp-capabilities (XEPs) in client

[Alexander Markov]

Hi everybody,

recently I've faced a problem that I need to disable PEP functionality 
in my pidgin client, as I get loads of events (nick, tune, mood, avatar) 
from my corporate jabber server. It generates a certain amount of 
traffic that can be an issue depending on where I connect from.

I looked everywhere and didn't find an ability to influence the caps 
pidgin advertises in <presence>

is there any way to disable unneeded capabilities in libpurple?

Thanks
Alexander
