Can not play radio streams any more

[SRU] The debdiff attached to LP: #1009436 backports cntlm-0.92.3-1ubuntu1 from Quantal to Precise.

[IMPACT]
When behind a corporate proxy requiring NTLM authentication, users are unable to play internet radio streams (worked in Lucid).

[Test Case]
Cntlm should be correctly configured and network proxy applied system wide as 127.0.0.1 port 3128 for HTTP, HTTPS and FTP, but not Socks.

Open Rhythmbox and add http://shouthostdirect12.streams.bassdrive.com:8200/ as a New Internet Radio Station. Highlight the newly added station and click Play.
0.91 behaviour: no music is heard and a red No Entry icon appears next to the station.
0.92 behaviour: music starts playing.

[Regression Potential]
Minimal: cntlm has no dependants and no dependencies besides libc6.
Please see LP: #1009436 for additional information.

Binary package hint: cntlm

Just upgraded to Maverick (10.10) and now I can't play radio streams any more
this worked fine in 10.04
  CNTLM - Accelerating NTLM Authentication Proxy version 0.35.1
Maverick version:
  CNTLM - Accelerating NTLM Authentication Proxy version 0.91rc6

Further issues:
* shutting down with sudo /etc/init.d/cntlm stop fails 'Stopping CNTLM Authentication Proxy: failed!"
* When debugging the first crtl-c gives me this message "^Ccntlm[27631]: Signal 2 received, issuing clean shutdown" but the process does not end (a second crtl-c works)

sudo cntlm -v -f -c /etc/cntlm.conf

output from the new version 0.91rc6:
