+== Troubleshooting ==
+=== Segmentation fault in Ubuntu 11.10 ===
+If the reconstructor crashes like that (numbers can vary):
+
+{{{
+$ ./3dbar.sh
+./3dbar.sh: line 17:  2296 Segmentation fault      python bin/reconstructor/gui.py
+}}}
+  
+the reason can be a bug in the 'python-vtk' package installed in your system.
+Unfortunately there is no automated way to fix it - you have to do it manually:
+
+1. Find a file named 'wxVTKRenderWindowInteractor.py'. It can be located
+   in '/usr/share/pyshared/vtk/wx/' directory or in similar location:
+ 
+{{{
+$ find / -name 'wxVTKRenderWindowInteractor.py'
+}}}
+
+2. Edit the file with your favourite ASCII editor. In the example editor 'vim'
+   is used and it is assumed that the path to the file is
+   '/usr/share/pyshared/vtk/wx/wxVTKRenderWindowInteractor.py':
+ 
+{{{
+$ sudo vim /usr/share/pyshared/vtk/wx/wxVTKRenderWindowInteractor.py
+}}}
+
+3. Near 350th line of the file find a following line:
+ 
+{{{
+                d = '_%s_%s' % (d[2:], 'void_p')
+}}}
+
+4. Add '\0' characters to the line to make it like below:
+
+{{{
+                d = '_%s_%s\0' % (d[2:], 'void_p')
+}}}
+
+5. Save the modified file.
+
+
+6. The bug should be fixed for now. Try running 3dBAR again. If this solution
+   doesn't work - let us know.
