taglist error on certain sources

[marcin at saepia.net]

Hi,

i got strange errors related to tag lists when I try to launch
following pipeline:

jackaudiosrc ! audioconvert ! lame ! id3v2mux ! filesink location=/dev/null

what's interesing, I don't receive them when I switch source element
to other one, e.g.:

audiotestsrc ! audioconvert ! lame ! id3v2mux ! filesink location=/dev/null

What causes them? What is the solution?

Below comes full log.

Thank you.

m.
