update failure

[blind Pete]

Hi, 

I'm running Mythbuntu 12.04 and the update manager has told me 
that, "New hardware support is available".  Clicking on install 
and upgrade does not have the desired effect.  What I get is, 
"Package dependencies can not be resolved", with the following 
details.  I have edited the white space to make it more obvious 
that the version numbers look OK.  

Not attempting to change to 14.04 (yet).  
Just using 12.04 LTS. 
12.04.1 -> 12.04.2 -> 12.04.3 -> 12.04.4 -> 12.04.5

The last step failed for no obvious reason.  My guess 
is that there is a version comparison algorithm that 
can not quite cope with the version designations actually 
used.  Some of them got longer rather than higher.  

Any thoughts?  Report a bug?  Against what?  

Edited cut'n'paste...
