New description:

 Pidgin is sending invalid Entity Capability IQ's to other clients then
 failing to validate the response capability.

 Pidgin recieves standard presence element when contact comes online:
 <presence from='stpeter at jabber.org' to='dmex04 at jabber.org'
 type='unavailable'><c xmlns="http://jabber.org/protocol/caps" hash="sha-1"
 ver="QgayPKawpkPSDYmwT/WM94uAlu0=" node="http://code.google.com/p/exodus"
 /><presence>


 Current response by pidgin:
 (This IQ should contain a Ver element however for whatever reason pidgin
 merges that element with the node element.)

 <iq type='get' id='purple9447bde0'
 to='dmex04 at jabber.org/Client1897507793'><query
 xmlns='http://jabber.org/protocol/disco#info'
 node='http://code.google.com/p/exodus#QgayPKawpkPSDYmwT/WM94uAlu0='
 /></iq>

 After pidgin reports error.
 jabber: Could not validate caps info from user. Expected
 QgayPKawpkPSDYmwT/WM94uAlu0=, got 9gS16i2awMWEb4Dm1krPWB2pOqI=

 This occurs every time a user comes online, If the same user signs online
 mutiple times, the 'got' result is different that also shouldnt happen as
 the clients ver did not change.

 The IQ pidgin should be sending looks like this:
 <iq type='get' id='purple9447bde0'
 to='dmex04 at jabber.org/Client1897507793'><query
 xmlns='http://jabber.org/protocol/disco#info'
 node='http://code.google.com/p/exodus' ver='QgayPKawpkPSDYmwT/WM94uAlu0='
 /></iq>
