Update error

[Douglas Phillipson]

When updating Feisty I get the following error I can't seem to resolve:

Selecting previously deselected package gmediaserver.
(Reading database ... 119303 files and directories currently installed.)
Preparing to replace gmediaserver 0.11.0-1 (using 
.../gmediaserver_0.12.0-1_i386.deb) ...

E: Sub-process /usr/bin/dpkg returned an error code (1)

I can't even remove gmediaserver with dpkg, I get:

sudo dpkg -r gmediaserver
(Reading database ... 119302 files and directories currently installed.)
Removing gmediaserver ...
Stopping gmediaserver: invoke-rc.d: initscript gmediaserver, action 
"stop" failed.
dpkg: error processing gmediaserver (--remove):

Any help would be appreciated...
