I said from time to time because I do not know exactly user scenario. Maybe there is one which always causes an error. I have rather large application and I have uncaught exception handler which sends me error information. I deployed non obfuscated version on my production server and trying to understand by stack traces what is going on. Line where the exception occurs is always in sources of Label. And It seems that exception occurs only on FF 3.0.x. I have many clients with FF 3.3.x and do not see exceptions from them. And I have a com.google.gwt.user.client.Timer scheduled with rpc calls with changes in UI. But I can't understand how it affects Label creation, as exception is thrown when Label is not attached to DOM tree. Only Document.get().createDivElement() called and result is stored in Label. And the exception is thrown before the element is attached to DOM tree.
