Okay, it looks like this was due to the fact that I was passing an apparently corrupt .wav file as an argument when starting audacity. It has nothing to do with the welcome screen.
The wav file was generated in Octave, so maybe it's actually a problem there (with the wavwrite function), but after launching Audacity and manually loading this file, audacity spins indefinitely at 100%. I've attached the file for reference. ** Attachment added: "Wav file which causes audacity to busywait using 100% CPU." http://launchpadlibrarian.net/12523033/test.wav -- 1.3.4 beta won't get passed welcome dialog -> 100% CPU https://bugs.launchpad.net/bugs/199992 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
