Version: (using Devel) Compiler: gcc OS: Linux Installed from: Compiled sources After updating kdesupport to revision 877309 Phonon does seem to be screwed up when using Xine backend. First of all, I have no sound from KDE, and second, starting any multimedia application will produce only a crash. Here I put the backtrace of Amarok crash.

Please recompile kdesupport/phonon with full debug info. Also please install libxine1-dbg. Then get a new backtrace and paste it here.
I installed the debugging symbols and recompiled phonon with debug info. This is the backtrace of amarok.

"plugin %s trovato" means "plugin %s found", right? If that's the case then I'm stuck to understand what's going on. A wild guess would be a translation error... Try to run it in the C locale. This is the code in libxine, and your backtrace shows that file == NULL, so it really shouldn't print "plugin %s found"... if (file) xine_log (this, XINE_LOG_PLUGIN, _("load_plugins: plugin %s found\n"), file->filename); else xine_log (this, XINE_LOG_PLUGIN, _("load_plugins: static plugin found\n"));
You're right, 'trovato' in italian means 'found'. If the C locale can be changed I'll do it to favor further debugging, but I don't know how to do.
As far as I know just switching all of KDE to English (untranslated is the C-locale) should also switch the libxine translations. So just go to System Settings...
I already have my KDE in english language. To be sure of all choices, I tried to run amarok in both Italian or English languages and the error was the same. Even restarting KDE each time. (isn't there a more comfortable way to communicate instead of bugzilla comments?)
Running in C locale makes the crash disappear. It seems to be an incorrectly translated string. Needs to be fixed in libxine.
*** Bug 174438 has been marked as a duplicate of this bug. ***
This was due to broken translations, and multiple levels failing to implement sanity checks which were meant to be present. It's currently being worked around by replacing the xine_log(_(...)) calls with xine_log("%s", _("...")) and we're fixing the translations and the tools. See <https://bugs.launchpad.net/ubuntu/+source/xine-lib/+bug/290768>.
