Recently active topics in Wuala tagged with encryption

hi there,

during my recent upload tests via filesystem integration method (see other thread http://getsatisfaction.com/wuala/topi... ) i somewhen realized that there are hugeloads of files in %temp%\wuala\ which wasnt the case in former builds of wuala.

there are also two directories in there (download and upload)

in the actual %temp%\wuala\ folder there seem to be a very big number of "original" files which i was trying to upload into the wuala store it seems.

the filenames have been changed somewhat to

hexnumber-originalfilename.extension

example:
f3edab22-mypicture.jpg
(hexnumber is maybe some hash/crc/crc32 or something)
the files are unencrypted, so i can actually use them with the appropriate application as they all hold the actual data (pictures, and so on....)

is this some bug? anyway related to my other thread? i suppose this is a huge security risk as even with reboots, wuala clients shutdown/restart these folders dont seem to go away or dont get empied nor cleaned up and the files can be seen by "anybody" who has access to the physical machine.

this is really weird. anyone else having this behaviour? win32/winxp that is. wuala426
