[GIS] Using CASE expression in QGIS data defined properties

Question

I try to use CASE expression in my data defined properties, like this:

CASE WHEN  "ASULKM1999" > 100000 THEN 5 END

ASUKASLKM is population information and "5" will be size of point symbol. However, when I click ok/apply, QGIS will turn this expression to funny, like

CONDITION:
- WHEN ASULKM1999 > 100000 THEN 5

And nothing happens. Sometimes result is "(no root)".

Is this a bug / feature or am I doing something wrong? Using QGIS 2.1 master on Win and Ubuntu.

This was bug in QGIS 2.1 (master). Will work on version 2.0.

Fix is under a construction.
