python - zip freezing PySide QFileDialog on Linux -

this code behaves different on linux(centos 7) , windows(win 10). variable src passed trough qfiledialog.getexistingdirectory(). on windows machine after clicking ok folder qfiledialog window closes on linux machine remains frozen until zip operation done.

 def zipfolders(src, dst, id=none):      #pers = 100/len(os.listdir(src))     #num = 0      if id == 'zipproject':         zipfile(dst, 'w', allowzip64 = true) zf:             root, dirs, files in os.walk(src):                 f in files, dirs:                     s in f:                         if not s == []:                             fullpath = os.path.join(root, s)                             filename = fullpath.rpartition(os.path.basename(src))[2]                             if filename == '':                                 filename = '.'+fullpath.rpartition(os.path.basename(src))[1]                             zf.write(fullpath, filename)                 #num += pers                 #self.progress.setvalue(num)
