Segfault in tutorial

Hello:
I'm trying to make the Bottle tutorial to work. I have SuSE 10.3 with an x86_64 architecture, gcc 4.2.1 and Qt 3.3.8. I compiled openCASCADE 6.2 after applying Jason Kraftcheck's occ6.2.patch. The tutorial compiles but I get a segmentation fault when starting. Here is the backtrace:

Program received signal SIGSEGV, Segmentation fault.
