 There seam to be a problem when Pidgin gets not proper avatar via xmpp
 protocol.

 When someone upload avatar which is broken img file (you have eg. top half
 of image, and rest is missing), then you can see top of image and bottom
 from other person avatar.

 Way to reproduce:
   1. you need to have one jabber contact with broken avatar
   2. open broken avatar contact in tab
   3. open another contact with avatart in tab
   4. double click on avatars to enlarge them
   5. switch betwean tabs few times

 For me its looks like or memory leak or memory for avatars is shared
 betwean tabs and there is no zerofill before update with new one.

 OS: Windows XP SP3

 Picture showing problem in attachment.
