Somehow mesh.fnMesh becomes overwritten by mesh.mesh

After readjusting the mesh volSize via Simulation->Mesh->Mesh Settings, we get the following error:

Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/pyfrp/gui/pyfrp_app.py", line 1756, in generateMesh
    self.editMesh()
  File "/usr/local/lib/python2.7/dist-packages/pyfrp/gui/pyfrp_app.py", line 1742, in editMesh
    ret=pyfrp_gui_mesh_dialogs.meshSettingsDialog(currEmbryo.simulation.mesh,self).exec_()
  File "/usr/local/lib/python2.7/dist-packages/pyfrp/gui/pyfrp_gui_mesh_dialogs.py", line 72, in __init__
    self.updateFnMeshLbl()
  File "/usr/local/lib/python2.7/dist-packages/pyfrp/gui/pyfrp_gui_mesh_dialogs.py", line 127, in updateFnMeshLbl
    self.lblFnMeshVal.setText("..."+self.mesh.fnMesh[-self.nCharDisplayed:])	
TypeError: 'GmshImporter3D' object has no attribute '__getitem__'

which clearly points that mesh.fnMesh now contains what should be in mesh.mesh. This either happens in pyfrp_mesh class itself or in settings dialog.
