Summary:                    [patch] chan_skinny crashes asterisk when parking a
call
Description: 
I have recently upgraded to Asterisk 1.6, from 1.4, and also acquired a
Cisco 7905 handset - so have now configured chan_skinny for the first time.
This seems to work in the main, apart from when I use the 'Park' softbutton
on the handset, which causes Asterisk to crash. Clearly, this shouldn't
happen!

I can dial the park extension just fine from the handset - it only crashes
if I press the softbutton.

I have checked out the latest SVN and the crash still occurs.

Happy to debug further if somebody can tell me how (I'm not an Asterisk
developer)

Thanks Dan.

I've applied the v2 patch but still get a crash with the softkey...

Am now heading out but will try again this evening!
