Ok, now I can reproduce it every time:

1. get this scroll-test mail dir[1]
2. there are two marked (and colored) messages, mark them as unread and
   make sure Sorting by thread date is enabled.
3. Go into another dir and go back to this one, the first unread
   message is selected and visible.
4. Press Next unread message button, the next unread message is
   correctly selected, but the scrolling is wrong and it is not visible!

I am giving a look at summary_select_row() in summaryview.c, I firstly
thought the problem could be with gtkut_tree_view_scroll_to_cell() but
it happens also if I replace this call with a plain
gtk_tree_view_scroll_to_cell(). It also happens with or without
alignment.

Any hint?
