I observe some very strange behaviour: my balance (as reported by getFunds call) jumps from one (correct) value to another (incorrect) value approximately once per minute, although no trading activity is in place:

2014-04-03 11:03:42 bter:    0.06835592btc, 26.44739516vtc
and so on.

Nothing suspicious in other parts of json (result is always true, etc).

I contacted support with detailed logs and json files, but their response is not encouraging as yet ("we'll look into it in later").

Has anyone run into the issue? Can anyone reproduce? Any ideas of a workaround?
