Please describe the problem:
Binary package hint: evolution

This looks a bit like ubuntu-bug #215643 although it is not exactly like.

When I try to drag-and-drop mails to certain folders, they "will not go in there". They "fly back" to where dragged from. Right-clicking the mail, choosing "Move to folder" and then clicking the misbehaving folder also does not work: the folder is simply not highlighted as selected.

I can move mail to other folders both by drag-and-drop and by the right-click menu.
If I try and create a new folder I can move mail to it.
I tried deleting the <folder>.cmeta, <folder>.ibex* files, but this did no difference.

Permissions on the <home>/.evolution/* are all read-write.
I have run evolution from a terminal, and no messages appear as I try the move.

Note the evolution accounts, data, etc were migrated from another ubuntu install (7.04 I think).
Now using 8.04, the "Summary and folder mismatch, even after a sync" bug is gone :). I get this bug instead o_O

The attachment is a video of the behaviour.
