synaptic freezes when installing packages

I checked both Adept and apt-get through konsole on KDE4 and they worked perfectly. I then tried Synaptic in 8.04 RC KDE3 and Synaptic worked. So, it looks like it is a KDE4 problem.

Synaptic freezes when done installing when installed on Kubuntu 8.04 kde4. To reproduce, install Kubuntu 8.04 kde4 and then install Synaptic. Install something with Synaptic, and it will freeze when done installing. It does not seem to damage the system, but is very annoying because Synaptic has to be killed from the system monitor or terminal.

It does not happen when Ubuntu is installed and then kde4 is installed. It only happens on Kubuntu 8.04 kde4.

I can confirm this bug. Synaptic works fine on ubuntu, but hangs after every install in kubuntu 8.04 'KDE 4 remix'. I guess it waits for the end of some process but for some reason doesn't get informed when this process ends.

I have the same issue and it does not just happen on Kubuntu only installs. I installed Ubuntu and then KDE 4 and I get the same problem when using Synaptic in KDE 4. My Nvidia graphics settings got messed up somehow and I had to do a fresh reinstall and still get this error when using Synaptic in KDE 4. It seems to finish the install and just hangs there.

Using kde 4.0.3, I can confirm this. But I think is related to synaptic + kdesudo. I tried gksudo synaptic and it works just fine (i.e. synaptic didn't froze).
I'll try upgrading to 4.0.4 to see if it's solved.

It's not fixed in KDE 4.0.4 nor in KDE 4.1 beta 1. I can also confirm that it only happens when running synaptic through kdesu (KDE4 version) but not with gksudo.

To me Synaptic works in Gnome but not in Kde 4.1 (from ppa repos), it freezes in the end. I quit synaptic and the packages are correctly installed.
