PPD lookup and printer auto-detection does not work as background thread

[Till Kamppeter]

Binary package hint: system-config-printer

In system-config-printer 0.7.70 on Gutsy it seems that the threading does not work.

If I click on the icon to add a new printer the first step of the add-printer wizard shows as blank window for several seconds. and does not allow entering the queue name. From the output on the console from which I have started system-config-printer I can see that in this time the PPD list and the list of available printers is polled from CUPS. I can only start entering the print queue name when this process has completed.

Expected behavior is that the PPD list and the printer auto-detection is done in a background process, so that I can enter the print queue name immediately and do not need to wait so long time when clicking "Forward" for the next step.

In addition, it makes a bad impression to the user to see a blank window.

Indeed

In fact i'd this bug at my home but i was not uptodate.
Now at work with latest hal-cups-utils, s-c-p pythin-cups this seems working right.

Can you verify ?

The problem occurs as described if I ssh into my Gutsy box from another machine and I start system-config-printer out of the ssh shell (on the desktop of the remote box).

If I am on the local desktop of the Gutsy box the behavior is different, but also broken:

The first page of the add-printer wizard is drawn correctly, but I cannot type anything into the field and the window does not redraw. The window gets usable again when the background process finishes.

I have done a complete update of my Gutsy box again ("sudo apt-get update; sudo apt-get dist-upgrade") and after that the add-printer wizard works as designed. The PPDs and available printers are polled in the background while enterin queue name and description.

The bug was fixed by somethinf (library?).
