What is your Phonon version ? Thanks I compile kde from trunk and update every night so ... But do you also compile kdesupport/phonon ? or do you use a global packaged version ? (that may be a possibility too) Thanks Phonon Version: 4.3.50 . of course ? I can not run beta1 4.3 without kdesupport? What Phonon backend do you use ?

It is not backend related. <apachelogger> comment 8 and 12 are fundamentally different crashes <apachelogger> #12 comes probably from VLC not implementing a streaminterface <apachelogger> Q_ASSERT(streamInterface); <apachelogger> relevant line of code ^ It is arguable whether Phonon should assert there, but not related to the original report... Is the original issue still reproducible? Changing status. Closing for lack of feedback. Please feel free to reopen if you can reproduce this with KDE 4.10.2 or later. |
