Recently active topics in Wuala tagged with quota

Hello folks,

pasting wuala -nogui's output seems the best way to me to describe the problem:

Wuala>version
Version Linux v105

Wuala>tradeStats
Average online time: 21.00%
Current limit: 2 GB
Last update: 3:48 PM
Locally stored data (according to the other users): 1.6 GB
Earned storage: 434 MB
Earned storage is split among 1 users of this computer

Wuala>showQuota
Quota: 2 GB
File Sizes: 24 MB
Base: 1 GB
Friend earned: 1 GB
Node earned: 0 B
Given: 0 B
Content use: 2.4 MB
List use: 22 MB
Earned: Earned: 0 B from 0 different nodes

Why does "tradeStats" ("Earned storage: 434 MB") still differ to "showQuota" ("Node earned: 0 B") even 17%-limit was hit a few days ago? Is it a bug or a feature? ;-)

br,
Kristof

P.S. #1: Client has been restarted a few times over the last week.
P.S. #2: Windows-client on a different machine neither mentions the earned storage by the Linux-node (Windows-client has been restarted a few times as well).
P.S. #3: My Wuala-username is Korwisi.
