New description:

 Pidgin is sending invalid Entity Capability IQ's to other clients then
 failing to validate the response capability eveytime the user signs online
 and everytime the user does something like request a user's info or open a
 chat.

 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=

 If the same user signs online mutiple times, the 'got' result is different
 even though 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>
