Bug#736822: Cannot purge/completely remove Steam

[Vlad Orlov]

Package: steam
Version: 1.0.0.39-1
Severity: normal

Hi,

I had Steam installed for some testing purposes I don't remember, and later I removed it.
It didn't get removed completely, there's a couple of files left:

$ ls -l /var/lib/dpkg/info/steam.*
-rw-r--r-- 1 root root   0 Jan 27 11:23 /var/lib/dpkg/info/steam.list
-rwxr-xr-x 1 root root 451 May 27  2013 /var/lib/dpkg/info/steam.postrm

I can't remove it with "apt-get remove" because it's counted as already removed:

$ sudo apt-get remove steam
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package 'steam:i386' is not installed, so not removed
0 upgraded, 0 newly installed, 0 to remove and 8 not upgraded.

But I also can't remove it completely with "apt-get purge":

$ sudo apt-get purge steam
Reading package lists... Done
Building dependency tree       
Reading state information... Done
The following packages will be REMOVED:
  steam:i386*
0 upgraded, 0 newly installed, 1 to remove and 8 not upgraded.
After this operation, 0 B of additional disk space will be used.

dpkg: error processing steam (--purge):
 subprocess installed post-removal script returned error exit status 10
Errors were encountered while processing:
 steam
E: Sub-process /usr/bin/dpkg returned an error code (1)

I really don't know what part of that script returns status 10, and what that code means,
so here I am, asking for some assistance.
