[apport] dpkg-preconfigure crashed with SIGSEGV in xcall_QGroupBox()

After submitting this bug report I closed adept_notifier and ran "apt-get update" then "apt-get upgrade".
There was on error that occurred in that process:
"Preparing to replace kubuntu-default-settings 1:7.04-21 (using .../kubuntu-default-settings_1%3a7.04-23_all.deb) ..."
"Unpacking replacement kubuntu-default-settings ..."
"Unknow argument for /var/lib/dpkg/info/kubuntu-default-settings.postrm"
Don't really know if this is related.

The problem described in this bug report was happened also in my Pc during the updates of yesterday.

Running Kubuntu 7.04 kernel 2.20.8-386
Apport just reported the "frontend" had crashed while apps were initializing during KDE start up. Debconf package was selected by Apport as the offending package.

Happened to me also, I`m using Kubuntu 7.04.
But for me it didn`t really crash, i couldn´t press next, so i pressed cancel,
after that adept updater said "Could not commit changes" and so on,
and stopped installing.

After posting my comment I closed adept and upgraded using console, it worked fine, didn`t give any errors or anything like that.

happened to me too, I can't use anymore adept update cause a few days ago as it was never ending stopping and crashing I lost totally control of my PC and it wasn't possible to stop it the right way. I had to switch off wrong way (power down) and then the fils system refused to start-up any more. i had tyo resintall again averything. I use the alternate amd64 6.10 that after hand I UPGRADE to feisty (editing source list). Reason is from the live cd rom it refuses to format and install in teh partition I want it goes to. BUT with the 6.10 alternate cdrom it does what I want then I just need to update. It goes fine and I can do some upgrade untill it complains for thoses missing values.

try this to get past the problem:
Open konsole
sudo apt-get update
sudo apt-get upgrade

The first will fetch the list of updatable packages.
The second will download and install them.
This will fix adept for you.

When Adept raised the Nice error, cancelling didn't seem to totally remove the debconf prompt.. Or rather, it possibly did, but the subsequent attempts to test Adept brought the issue up again, only the Nice warnings were no longer shown.

Trying command line apt-get upgrade complains that debconf was still locking the db. So I restarted PC, and during shutdown, the nice error then re-appeared from whereever it had been hiding.

Upon restart, apt-get upgrade worked without issue.

I ran apt-get upgrade from the command line as suggested and the nice error persisted, but now in a ncurses-like CLI (see attachment).

Therefore it has nothing to do with adept but with the package *x11-common*. If I de-select it, the upgrade runs just fine. Kubuntu Herd 5 here.

Here the same.

Feisty 7.04 Herd 5 (upgraded from 7.04 Herd 2)

Same here. Atleast I think it's the same.

This bug is also reported in Debian bug tracker as #413716.

Sorry, Debian bugs #413716 is a clone of #413509. According to Debian developers bug #413509 is fixed with a patch in the version 1.5.13 of debconf included in Debian unstable.

This is also bug #68267 which is now fixed in feisty (was a bug in x11-common configuration script).
In my opinion, the fact that it caused debconf to SIGSEGV have not enough been examined enough however.

Now, I am not too sure how to handle this (I means bug #68267 is considered close with 10 duplicates, this one have 38, still open on libqt-perl, which is not clear to me what it does have to do with the bug, Debian fixing one way and Ubuntu an other).

Latest version of debconf 1.5.14 claims to fix this.
