I have been using semantic through the ECB package for over a year now. I normally use semantic for C/C++ files and everything works like a charm. However when I want to browse / edit Python files, it frequently happens that Emacs gets stuck in an infinite loop.  The last message I get is "wisent-parse-stream: Invalid-start symbol bovine-inner-scope". After that, the only way out is to kill the Emacs process. This problem occurs even with small Python files. It also does not seem to be related to ECB, the problem occurs even with ECB deactivated.

Does anybody have an idea what is causing this problem ?

I am currently using semantic-1.0beta2a and Emacs (on Windows XP).

With kind regards,
