sge qjobinfo __repr__ raises exception (silently)

[bpinsard]

Sorry, I am finding again some weird deep dark hidden bug. =]
The changes to the following line raises exception:

nipype/nipype/pipeline/plugins/sge.py

Line 53 in 6c6cd78

def __repr__(self):

but is caught by run_qstat here:
https://github.com/nipy/nipype/blob/master/nipype/pipeline/plugins/sge.py#L264
when it calls _parse_qstat_job_list which calls repr in:

    199                 sge_debug_print("Updating job:  {0}".format(
--> 200                     self._task_dictionary[task_id]))

So that it loops for a long time, and is not able to retrieve job status and acknowledge their completeness.

The exception it raises is:

nipype-0.13.0_g8144fb3.dev-py2.7.egg/nipype/pipeline/plugins/sge.pyc in __repr__(self)
     55             self._job_num, self._job_queue_state, self._job_slots,
     56             time.strftime("%Y-%m-%dT%H:%M:%S", time.gmtime(self._job_time)),
---> 57             self._job_queue_name, self._qsub_command_line)
     58 

ValueError: Unknown format code 'd' for object of type 'unicode'

because the _job_slots attribute is not a integer but a string from xml as defined here (or the string 'unknown'):
https://github.com/nipy/nipype/blob/master/nipype/pipeline/plugins/sge.py#L174

What does _job_slots field is supposed to contain as information?
