[galaxy-dev] RuntimeError: maximum recursion depth exceeded while calling a Python object ( when trying to run blast)

Hello, I'm using the latest Galaxy distribution and am getting an error when trying to run any of the ncbi blast tools. Error executing tool: maximum recursion depth exceeded while calling a Python object This is what I find in paster.log I'm attaching it because the traceback is 1500 lines long. Thanks in advance for your help, Liisa
