Marek, please could you have a look at it, I think you were already solving almost the same problem.
Problem is with synchronous cleaning of wstcref file of component which failed to be deserialized. Fix is to make cleaning asynchronous. Modified: core/src/org/netbeans/core/windows/layers/TCRefImpl.java r.1.51
Verified.
