Hmmm, I'm guessing someone cast a pointer to an integer somewhere. This is the most common problem with programs not working on Alpha (remember 64-bit address and 32-bit ints). And judging that: 540847136 == 0x203CAC20 and the rest of the address in the backtrace have 0x00000001 in the upper four bytes...
I thought that there was a warning that was spit out when you compiled on Alpha? Wolfi, is it possible to get an Alpha build log?
The build-log of the debian package is available at http://buildd.debian.org/fetch.php?&pkg=inkscape&ver=0.39-1&arch...

and such. Another warning which is probaly unrelated to this problem is if alpha-linux-g++ -DHAVE_CONFIG_H -I. -I. -I.. -DXTHREADS -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/X11R6/include -I/usr/include/atk-1.0 -I/usr/include/pango-1.0 -I/usr/include/freetype2 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/libxml2 -I/usr/lib/sigc++-1.2/include -I/usr/include/sigc++-1.2 -Wall -W -Wpointer-arith -Wcast-align -Wsign-compare -Woverloaded-virtual -Wswitch -Wno-unused-parameter -g -O2 -MT spiral-context.o -Molekular-Dynamik -MP -MF ".deps/spiral-context.Tpo" \ -c -o spiral-context.o `test -f 'spiral-context.cpp' || echo './'`spiral-context.cpp; \ then mv -f ".deps/spiral-context.Tpo" ".deps/spiral-context.Po"; \ else rm -f ".deps/spiral-context.Tpo"; exit 1; \ fi spiral-context.cpp: In function `void sp_spiral_drag(SPSpiralContext*, NR::Point, unsigned int)': spiral-context.cpp:440: warning: `sp_view_set_status' is deprecated (declared at view.h:194)
It looks like we should get rid of this, too.
