Hi, i don't know why, but sometimes some applications doesn't start any longer or i get symbol lookup errors. The same applications had no problems a day before. For example this morning: $ psi psi: symbol lookup error: /usr/lib64/qt-3.3/lib/libqt-mt.so.3: undefined symbol: _ZNK20QDomDocumentFragment18isDocumenvFragmentEv $ rpm -ivh --force qt-3.3.4-15.4.x86_64.rpm -> psi works $ yum --help python: Python/ceval.c:762: PyEval_EvalFrame: Assertion `stack_pointer >= f->f_valuestack' failed. Abgebrochen $ yum instal firefox Traceback (most recent call last): File "/usr/bin/yum", line 4, in ? import yum File "__init__.py", line 35, in ? ValueError: bad marshal data $ rpm -ivh --force python-2.4.1-2.x86_64.rpm -> yum works Any hints? -- Ciao Kai Homepage: http://kai.iks-jena.de/ Weblog: http://rabenhorst.blogweb.de/ OpenPGP: D6E995A0 Jabber: kraven@xxxxxxxxxxxxx
