Comment: I had exactly the same problem when i tried to add wav-files. After removing python-gst-0.8.3-1 and keeping python-gst0.10 serpentine at least began to load the wav-files until it crashed. Here's the output with python-gst-0.8.3.1 installed: ----------snip-------------- Traceback (most recent call last): File "/usr/lib/python2.4/site-packages/serpentine/operations.py", line 290, in __start_next oper.start() File "/usr/lib/python2.4/site-packages/serpentine/mastering.py", line 179, in start l.on_finished (e) File "/usr/lib/python2.4/site-packages/serpentine/operations.py", line 318, in on_finished self.__start_next() File "/usr/lib/python2.4/site-packages/serpentine/operations.py", line 290, in __start_next oper.start() File "/usr/lib/python2.4/site-packages/serpentine/mastering.py", line 106, in start oper = audio.gvfsAudioMetadata(self.hints["location"]) File "/usr/lib/python2.4/site-packages/serpentine/audio.py", line 350, in gvfsAudioMetadata filesrc.set_property ("location", uri) AttributeError: 'NoneType' object has no attribute 'set_property' --------snap------------- On the second attempt (with --debug option) and third attempt (normal run without --debug option) adding of the wav-files worked. Perhaps the crash on the first attempt without python-gst-0.8.3-1 was a result of an old python-gst instance still in the cache. Nevertheless, serpentine either needs a version-checking for python-gst or should conflict with < python-gst-0.10 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
