There seems to be a problem with detrend

dgelss:lwork=134
Traceback (most recent call last):
  File "io.py", line 36, in ?
    detrend_intyou = signal.detrend(intyou,-1,'linear')
  File
"/usr/local/lib/python2.1/site-packages/scipy/signal/signaltools.py",
line 1107, in detrend
    coef,resids,rank,s = linalg.lstsq(A,newdata[sl])
  File "/usr/local/lib/python2.1/site-packages/scipy/linalg/basic.py",
line 277, in lstsq
    overwrite_b = overwrite_b)
flapack.error: (lwork>=3*minmn+MAX(2*minmn,MAX(maxmn,nrhs))) failed for
2nd keyword lwork

Any idea or suggestion ?
