 If pidgin is closed, when the config files are written (during windows
 crash for ex) they are broken

 It would be easy to solve this:
 make an backup of the old config file -> xml.bck
 write the new config file -> xml.tmp
 copy the new conig file over the new one  -> .xml
 look if it's the same, like the tmp one (xml.tmp=.xmp?)
 look if it's usable
 rename the backup into xml.oldbck

 if pidgin loads it should check if a xmp.bck it there, if so it should ask
 to load it
