Empty foldernames (as they could be created through nametrans) were failing as the uidvalidity and status files names as determined by folder/Base.py:getfolderbasename() lead to invalid file names ''. Fix this by handling empty file names and translating them to '.' which leads to the special file name 'dot'. (this special value existed before and was not invented by this patch) Signed-off-by: Sebastian Spaeth <Sebastian@SSpaeth.de> Signed-off-by: Nicolas Sebrecht <nicolas.s-dev@laposte.net>
