Hi, I'm running a local instance of Galaxy and no matter what tool I run I get the following error: Error executing tool: maximum recursion depth exceeded while calling a Python object In the log file: galaxy.tools ERROR 2013-01-25 14:06:54,375 Exception caught while attempting tool execution: Traceback (most recent call last): File "/Galaxy/galaxy_dist/lib/galaxy/tools/__init__.py", line 1776, in handle_input _, out_data = self.execute( trans, incoming=params, history=history ) File "/Galaxy/galaxy_dist/lib/galaxy/tools/__init__.py", line 2103, in execute return self.tool_action.execute( self, trans, incoming=incoming, set_output_hid=set_output_hid, history=history, **kwargs ) File "/Galaxy/galaxy_dist/lib/galaxy/tools/actions/__init__.py", line 203, in execute chrom_info = build_fasta_dataset.get_converted_dataset( trans, 'len' ).file_name File "/Galaxy/galaxy_dist/lib/galaxy/model/__init__.py", line 1161, in get_converted_dataset new_dataset = self.datatype.convert_dataset( trans, self, target_ext, return_output=True, visible=False, deps=deps, set_output_history=False ).values()[0] File "/Galaxy/galaxy_dist/lib/galaxy/datatypes/data.py", line 467, in convert_dataset converted_dataset = converter.execute( trans, incoming=params, set_output_hid=visible, set_output_history=set_output_history)[1] File "/Galaxy/galaxy_dist/lib/galaxy/tools/__init__.py", line 2103, in execute return self.tool_action.execute( self, trans, incoming=incoming, set_output_hid=set_output_hid, history=history, **kwargs ) File "/Galaxy/galaxy_dist/lib/galaxy/tools/actions/__init__.py", line 203, in execute chrom_info = build_fasta_dataset.get_converted_dataset( trans, 'len' ).file_name File "/Galaxy/galaxy_dist/lib/galaxy/model/__init__.py", line 1161, in get_converted_dataset new_dataset = self.datatype.convert_dataset( trans, self, target_ext, return_output=True, visible=False, deps=deps, set_output_history=False ).values()[0] File "/Galaxy/galaxy_dist/lib/galaxy/datatypes/data.py", line 467, in convert_dataset converted_dataset = converter.execute( trans, incoming=params, set_output_hid=visible, set_output_history=set_output_history)[1] File "/Galaxy/galaxy_dist/lib/galaxy/tools/__init__.py", line 2103, in execute return self.tool_action.execute( self, trans, incoming=incoming, set_output_hid=set_output_hid, history=history, **kwargs ) File "/Galaxy/galaxy_dist/lib/galaxy/tools/actions/__init__.py", line 203, in execute chrom_info = build_fasta_dataset.get_converted_dataset( trans, 'len' ).file_name File "/Galaxy/galaxy_dist/lib/galaxy/model/__init__.py", line 1161, in get_converted_dataset new_dataset = self.datatype.convert_dataset( trans, self, target_ext, return_output=True, visible=False, deps=deps, set_output_history=False ).values()[0] File "/Galaxy/galaxy_dist/lib/galaxy/datatypes/data.py", line 467, in convert_dataset converted_dataset = converter.execute( trans, incoming=params, set_output_hid=visible, set_output_history=set_output_history)[1] File "/Galaxy/galaxy_dist/lib/galaxy/tools/__init__.py", line 2103, in execute return self.tool_action.execute( self, trans, incoming=incoming, set_output_hid=set_output_hid, history=history, **kwargs ) thousands of lines here...ending with...
