Thanks for you help @vikram.
Just wanted to let you know this.
The 0.5.2 workaround worked fine, but CNY funds were still missing. (about 90% of the balance)
Just 1 minute ago i was buying USD with BTS using this "problematic" account.
After i submitted the ask and typed "balance" to see the new USD ... magically all the CNY appeared (apart from the recently purchased USD).
strange ... but all funds are ok.
