I have the same problem on a 32bit machine since I upgraded to karmic. I noticed when running xsane with valgrind that some uninitialized values are used just before the X errors. I tried to download the source code and compile it with --enable-debug so that I can get a valgrind log with correct backstacks. I'm attaching the log of the errors I got.
