The thread should exist, looking at the code path in the semaphore lib. The thread_id used for the prio-get is coming fron an ipc-wait so the thread should be there (in the sense there's a thread at all). The thread-lib might have some other state than ACTIVE for this thread. If you look in the debugger, the thread is there and its state is fine? If it happens, is it a permanent error or just sporadic? Does it happen during some setup phase or after that when things have settled?
