Там в метаданных к каждому thumbnail есть поле (tEXt::Thumb::URI),
которое содержит URI к исходному файлу!
Если этого поля нет, то thumbnail не Free Desktop compliant, удаляй ;)
Шлю скрипт на питоне (использует gtk gnomefvs glade =)
При желании от туда можно выцепить полезные строчки кода, которые делают
реальную работу =)
