>Description:
The current version of cad/qcad, 3.4.6.0, will exit with a SEGV when attempting to print a drawing or export to PDF.  This happens on amd64 but not on i386.  In fact, if built in a i386 chroot (like wine) it will work on the same amd64 system where it fails if built natively.

This has been a problem for at least the last few versions, and possibly longer.  
>How-To-Repeat:
1. Build and install cad/qcad on an amd64 system
2. Start it up
3. In the file menu select either "Print" or "PDF Export" - you don't have to actually create a drawing
4. If you selected "PDF Export" then follow the prompts for the file to save
5. qcad will exit with a SEGV
>Fix:
This is not a very easy work around, but cad/qcad can be built as a 32 bit application on an amd64 system, pretty much like one would do for emulators/wine.  You have to set up a 32 bit chroot, build and install it there, then fix up all the symbolic links that get created with absolute paths.  After all that you need to specify an appropriate LD_32_LIBRARY_PATH each time you want to run qcad.  But it will work that way.
