[Tilesathome] Upload does not upload all zip files

[pml1 at wuzel.de]

Seen with client revision 10004 (I do not know since when):

Running "perl tilesGen.pl upload" fills the directory "uploadable", then 
uploads one file, then complains that this file (which was just uploaded 
successfully) does not exist and stops. Running upload again uploads the next 
file.

The same thing seems to happen in loop mode.
