To debug the Windows version of Inkscape, do the following;

1. Place the files inkscape.dbg and gdb.exe inside the Inkscape folder

2. Open a command window [Start Menu -> Run -> command (enter)]

3. type the following
     ..> gdb (enter)
     (gdb) file inkscape.exe inkscape.dbg (enter)
     (gdb) run {filename optional} (enter)

4. The debugger will get part way and then give an error about xml. Type;
     (gdb) continue (enter)

5. This will start Inkscape, but the normal open command will not work to
open files, as it will hang. You must use the import command instead.

6. Repeat the steps to produce the crash/problem
7. Go to the command window and type;
     {error message of some sort}
     (gdb) bt

8. This will now give some more information. You will need to highlight the
text in the command window and then right click once to copy. Then paste this
into a bug report at https://bugs.launchpad.net/inkscape/

Note: If unable to copy, right click on the icon at the top left hand of the 
command window, then select 'Properties', and then under the 'Options' tab
tick 'Quick Edit Mode'. You should now be able to copy from or paste to the
command window using the right mouse button.
