[packagekit] exclude some upgrades

[Matej Cepl]

How is pk-update-viewer supposed to work? Is that list of packages just 
informative or there is just some functionality hidden behind it? What I 
mean is this:

[matej at hubmaier ~]$ pkcon update-system
    [..........................................................]    
0%          
Error: dep-resolution-failed : Error in Dependency Resolution;Missing 
Dependency: gecko-libs = 1.8.1.9 is needed by package yelp;Missing 
Dependency: gecko-libs = 1.8.1.9 is needed by package epiphany;Missing 
Dependency: libtotem-plparser.so.9()(64bit) is needed by package 
rhythmbox;Missing Dependency: libmtp.so.6()(64bit) is needed by package 
rhythmbox;Missing Dependency: libdhcp6client-0.10.so.0()(64bit) is needed 
by package nash;Missing Dependency: libdhcp6client-0.10.so.0()(64bit) is 
needed by package mkinitrd
update-system runtime was 26.2 
seconds                                          
[matej at hubmaier ~]$

OK, this is probably all fault of using Fedora Rawhide which is messy. 
However, with yum I could do yum upgrade --exclude=something, but neither 
pkcon nor pk-update-viewer (to the best of my knowledge) doesn't have 
anything like exclude. Would it be possible to click on items in the pk-
update-viewer list and check exclude for that package (similar to what 
pup does, actually)?
