Since you are using a tablet, it's most likely the same issue as
Bug #284546 in Inkscape: “Crash on using calligraphy tracing tool with wacom tablet”.

Sorry, no idea what might have happened.

Thanks ~suv it is indeed a wacom tablet. when i went to bugtracker it was not one of the bugs it offered as possibilities but that may have to do with how I wrote the description.
I am interested to know about the backtrace thing though - you must be familiar with the gdb program (although i think you are on a MacOS) is the backtrace a saved file, or just output that shows up in the console? is the output I got

Program exited with code 03.
(gdb) bt
No stack.
(gdb)

all the information it gives?

As far as I understood the crash is not limited to Wacom tablets, but happens with whatever tablet is used, across all platforms.

I'm on Mac OS X, and my knowledge about gdb is limited (just the basics). And I haven't used it on Windows… But backtrace output (bt) is to the console/terminal like the other output of gdb. See the gdb documentation about Logging Output options if you want to save the output of gdb commands to a file.

Did you install the debug files? They can be downloaded from sf.net for 0.47, or from modevia for each snapshot build (AFAIK you have to place the unpacked files inside the Inkscape folder).
Some tips can be found in the Inkscape Wiki: Debugging Tips for Windows (I hope they are still current).

I did download them at the same time as the build itself posted on http://inkscape.modevia.com/win32/?M=D
But I have never debugged before so I will take a look at the info.
Thanks!
