[packagekit] transaction errors from the yum backend

[Matthias Clasen]

I finally tried to find out where the detailed message about conflicts
gets lost.

Running update-system.py with conflicting updates ends with:

error	transaction-error	Error in Transaction Processing;

which comes from around line 922 in yumBackend.py:

            except yum.Errors.YumBaseError, msgs:
                retmsg = "Error in Transaction Processing;" + ";".join(msgs)
                self.error(ERROR_TRANSACTION_ERROR,retmsg)

Adding a   print >>sys.stderr, "see: " + str(msgs) in there reveals
that the details are there:

see: ['ERROR with rpm_check_debug vs depsolve:', 'Package otherapp
conflicts with someapp.', 'Please report this error in bugzilla']


I'm not enough of a python programmer to figure out why the join()
call doesn't work...
