It looks like your problem is with the LinePatternSymbolizer, similar to Andy's experience. It looks like the copy of the mapnik library used for this test (/usr/lib/libmapnik.so.0.7) was not built with debug enabled (scons DEBUG=True). If it included the debug information then there would be additional data about the function parameters, filenames and line numbers. It would be useful if you could try to get this extra information because it really helps narrow down the specific problem case. I will take a look at the code and try to guess where the issue might occur but it will be impossible to know for certain that we have found the problem without this additional debug information.
