Hi.

Back to the problem after a while.
Here is a debug output that leads to problem.. For me it seems like
scan start of second album fails. (But hey, my last guesses in this
list were not very good ones). The only photo in second album is
2010_10_10_IMG_3024.CR2 and I do not see that the exiv2 had started to
read it.
