[CS4-Win] Thread problem while porting

Question

I'm porting my plugin from CS3 to CS4 and I get following error while trying to open document:
Thread local data subsystem not initialized for this thread.
BeginPublicThreadBottleneck has not been called. (known leopard nav services problem here)
In CS3 this code works.
I use Windows native threads in my plugin.
Also I've got several warnings with following text:
CTUnicodeTranslator - Calling into single threaded CoolType from a thread - not safe
Can anybody help?

I'm not too familiar with Windows threads, but you need to initialize the TLS, see http://msdn.microsoft.com/en-us/library/ms686991(VS.85).aspx
If you look in the source/public/includes/CTUnicodeTranslator.h, you can see that there are methods for getting an instance of the converter. This may give you problems when using multiple threads, i.e. several threads may access a the same state-based converter simultaneously resulting in in-correct conversions. Strange though, since Adobe is preparing to make InDesign multithreaded.
