lxml occasionally goes crashing on me, with an error message and backtrace like the one below. Usually, the same program runs just fine if I try again. What can I do to track down the cause? *** glibc detected *** python: free(): invalid pointer: 0x0a0388cb *** ======= Backtrace: ========= /lib/libc.so.6[0x1d3b16] /lib/libc.so.6(cfree+0x90)[0x1d7070] /usr/lib/libxml2.so.2(xmlNodeSetName+0xa5)[0x68fc0c5] /home/stp02/salo/lib/python/lxml-2.1.2-py2.4-linux-i686.egg/lxml/etree.so[0x3b988f] /usr/lib/libpython2.4.so.1.0[0x5437d83] /usr/lib/libpython2.4.so.1.0(PyObject_GenericSetAttr+0x104)[0x5455b84] /usr/lib/libpython2.4.so.1.0(PyObject_SetAttr+0xbb)[0x54561db] /usr/lib/libpython2.4.so.1.0(PyEval_EvalFrame+0x2d51)[0x548cd91] /usr/lib/libpython2.4.so.1.0(PyEval_EvalCodeEx+0x896)[0x548fc76] /usr/lib/libpython2.4.so.1.0(PyEval_EvalCode+0x63)[0x548fd03] /usr/lib/libpython2.4.so.1.0[0x54acad8] /usr/lib/libpython2.4.so.1.0(PyRun_SimpleFileExFlags+0x198)[0x54ae1e8] /usr/lib/libpython2.4.so.1.0(PyRun_AnyFileExFlags+0x7a)[0x54ae8ca] /usr/lib/libpython2.4.so.1.0(Py_Main+0xb85)[0x54b52d5] python(main+0x32)[0x80485b2] /lib/libc.so.6(__libc_start_main+0xdc)[0x180dec] python[0x80484c1] -- filip salomonsson
