------- Comment #9 from Stanislav Brabec  2009-05-07 17:00 UTC -------
Note that it still may be a problem of gstreamer, as it sometimes show:

*** glibc detected *** /usr/bin/gst-launch-0.10: malloc: top chunk is corrupt:
0x0000000000821e00 ***

After setting breakpoint to id3_ucs4_copy and stepping in gdb by "n" it
generated a different backtrace:

Program received signal SIGSEGV, Segmentation fault.
