Stop command sometime fail

[mbret]

Hello, it appears that sometime (rather often) the stop command fail.

COMMAND: stop []
stdout: A: 1.5 (01.5) of 0.0 (unknown) 9.3% 3%
stdout: A: 1.5 (01.5) of 0.0 (unknown) 9.2% 3%
stdout: A: 1.5 (01.5) of 0.0 (unknown) 9.2% 3%

Here is the failed command. The stream continue.

COMMAND: stop []
stdout: A: 0.5 (00.4) of 0.0 (unknown) 0.0% 2%
stdout:
EOF code: 4

Here is a success stop.

I'm testing with this stream http://cdn.nrjaudio.fm/audio1/fr/40101/aac_576.mp3?origine=fluxradios

Also it seems to works fine with mp3 however.
