Audio thread panics with E32User-CBase 47 if Music Player running

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Play music in Music player
2. Switch to Mobbler
3. Start a Last.fm radio station

What is the expected output? What do you see instead?
Expected: It would be nice to pause the music player (issue 123), but it 
used to play both at once.

Actual: Music Player keeps playing. A playlist is loaded, and the first 
track attempts to start, but it says "Application closed: Local-c8309210 
E32User-CBase 47". It immediately skips to the next track and continues to 
show the same error, until you manage to go offline or stop the radio.

This is new since the audio thread.

What version of the product are you using? On what operating system?
* Mobbler 0.3.4 dev
* Nokia N95 8GB v30.0.018 / 23-07-08

E32User-CBase 47:
"This panic is raised by the Error() virtual member function of an active 
scheduler, 
a CActiveScheduler. This function is called when an active object’s RunL() 
function 
leaves. Applications always replace the Error() function in a class derived 
from 
CActiveScheduler; the default behaviour provided by CActiveScheduler raises 
this 
panic."

A quick fix could be to simply not allow the radio to start if the Music Player 
is 
playing. And as issue 123 is tricky to fix, it would sort that too. Thoughts?

Of course, the panic should still be fixed. It would still occur when playing 
audio 
that doesn't get scrobbled by Mobbler, like mp3s shorter than 30 seconds or 
with 
missing artist tags.

Ain't this the same issue I complained a month ago? Read issue 235 for more

Now I re-read issue 235, it does indeed sound the same bug. The discussion on 
that 
issue went on further about how to make Mobbler control the Music Player more 
fully 
and it got turned into an enhancement.

Let's keep this issue to deal with the bug, and issue 235 to deal with the 
enhancements discussed in detail there.

Thanks for pointing it out!

I thought that if you implement RunError on an active object then you shouldn't 
get
this.  Perhaps this has been done incorrectly or I am wrong about this.  
Shouldn't be
too difficult to fix.

Yes, I think that we should stop radio if you start the music player and not 
allow
radio to be started if the music player is playing.  This is to stop things 
like this
and stop stop the scrobbling functionality from getting confused.

This has been fixed in issue 123.

Panic still to be fixed in this issue.
