Muon Software Updates hangs after side-by-side request

[kmulder]

doing software updates for samba-common

Muon prompted with
"What do you want to do about modified configuration file smb.conf?"

I first chose "show the differences between the versions", i looked at the diff output and i think the option was "Continue". It returned to the same Muon software updates screen with the same prompt.

I then chose "show a side-by-side difference between the versions". At this point the Muon interface screen "locked up". The Back and Continue buttons are grey'd out and nothing is happening.

my system is a fresh build in the last 7 days:
:~$ uname -a
Linux kmnix 3.0.0-17-generic #30-Ubuntu SMP Thu Mar 8 20:45:39 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

looking at the system monitor all processes, tree view i find:

qaptworker
  qaptworker
    dpkg
      frontend
       samba-common.po
          ucf

Status changed to 'Confirmed' because the bug affects multiple users.

I encountered similar issue during samba-common update when I was prompted for what to do with smb.conf.

I chose the same side-by-side comparison as kmulder, clicked Continue and got exactly same behavior. Process tree is same regarding qaptworker. My Ubuntu release and muon version are also the same, uname says version is 3.0.0-16-generic #29-Ubuntu SMP Tue Feb 14 12:49:42 UTC 2012 i686 athlon i386 GNU/Linux

I've fixed this behavior for QApt2.
