Comment 27 for bug 35112

Can confirm this in Gutsy. Seems to happen with VBR settings. In Gutsy (for me) there's also the problem, that pipelines including "xingmux" will not appear to be selected in sound-juicer, though are listed in gstreamer pipelines.

However, instead auf xingmux I tried ffmux_mpeg (ffmpeg packages) it works better, but still quite often totally wrong lenght information in totem, rhythmbox (especially) and nautilus.

Without ffmux_mpeg or xingmux (which does not work at all) results are even worse. Personally I don't need mp3 support, but at least when hardy gets released I will recommend ubuntu to more non-technical friends and family. Some of them need correct VBR mp3s. I think mp3 with CBR is not an option. ;-) But the VBRs make problems with many apps, for example with serpentine, when burning an audio cd. If you have many 3-4 min songs, which are displayed as 12 or 15 min songs, you can not measure how much space on the cd will be used.

PS: I noticed with "checkmp3" that nautilus displays the VBR rate also wrong, it shows only the lowest rate used (VBR_LOW) though it must be VBR_AVERAGE.
