Here's an example test.catalog:

I've checked that the package hello is indeed installed.

Here's an example Python script:

It displays this dialog:
Install packages in catalogue?
The following packages are marked to be installed from the catalogue:
| | The classic greeting, and a good example
| | hello-2.4-3 (i386)
| Help|                     | Close | Install |

After clicking install, it fails with this exception stack:

Running gpk-install-catalog test.catalog gives me these results:

First dialog:
Do you want to install this catalogue?
/home/david/test.catalog
| Help|         | Close | Install |

Second dialog after clicking install:
Install packages in catalogue?
The following packages are marked to be installed from the catalogue:
| | The classic greeting, and a good example
| | hello-2.4-3 (i386)
| Help|         | Close | Install |

Third dialog after clicking install, modal on top of a progress dialog:
Failed to install package
Unknown error. Please refer to the detailed report and report in your 
distribution bugtracker
+ More details
| could not do simulate: Package hello is already installed
                                 | Close |

I can't find a way around a dialog being displayed in this case.

Thanks, Richard!
