[Crash-catcher] another case when abrt fails to install debuginfo

[Jiri Moskovcak]

Hi,
yesterday I was testing the latest release and I noticed that yum fails 
to install debuginfo when previous yum transaction was cancelled. 
packagekit just fails to install packages complaining that there are 
some unfinished transactions and we get bt full of '?'. We really should 
pass these errors to user and make him resolve it. Or if we don't have 
debuginfo then we shouldn't even try to get bt? What do you think?
