[tauruslib-devel] taurusimage: getOpenFileName returning unicode list

[Teresa N. <mar...@de...>]

Hello,
         I have a problem  with the taurusimage widget, when I want to give
a file name for saving or exporting the image (using 'Save as ...' or 
'Export data ...'
  from the menu opened when clicking on the image). The name that I give to
  the QFileDialog window that is opened is seen as an unicode list, 
instead of
  as an string, I mean, it becomes, ex.

  [u'/', u'h', u'o', u'm', u'e', u'/', u't', u'n', u'u', u'n', u'e', 
u'z', u'/', u't', u'a', u'u', u'r', u'u', u's', u'_', u'g', u'u', u'i', 
u's', u'/', u'I', u'm', u'a', u'g', u'e', u'V', u'i', u'e', u'w', u'e', 
u'r', u'/', u't', u'e', u's', u't', u'.', u'p', u'n', u'g']

  instead of:


/home/tnunez/taurus_guis/ImageViewer/test.png

  And with this I get the error:


File "/usr/lib/python2.7/dist-packages/guiqwt/qthelpers.py", line 66, in 
exec_image_save_dialog
     io.imwrite(filename, data)
   File "/usr/lib/python2.7/dist-packages/guiqwt/io.py", line 395, in 
imwrite
     iohandler.get_writefunc(ext)(fname, arr, **kwargs)
   File "/usr/lib/python2.7/dist-packages/guiqwt/io.py", line 155, in 
get_writefunc
     ftype = self._get_filetype(ext)
   File "/usr/lib/python2.7/dist-packages/guiqwt/io.py", line 143, in 
_get_filetype
     raise RuntimeError("Unsupported file type: '%s'" % ext)
RuntimeError: Unsupported file type: ''


I have this problem since the operating system of my computer was 
changed from
  debian7 to debian8, with the following changes in pyqt and guiqwt 
versions:

debian7:
python-guiqwt_2.1.6-4_amd64.deb
pyqt4-dev-tools_4.9.3-4_amd64.deb

debian8:
python-guiqwt_2.3.1-1_amd64.deb
pyqt4-dev-tools_4.11.2+dfsg-1_amd64.deb

In both cases the python version was 2.7 and taurus 3.6.
Do you have any idea why the problem happens, and how could be solved?.
Thanks a lot.

                           Regards,
                                              Teresa
