Major system-wide crash on Composer when paper-size option is clicked.

[Thaddeus]

All my Ubuntu 10.10 64bit crashes when I click on the paper-size (General tab) ComboListBox to adjust the paper size: QGIS completely disappears along with everything that was running and a second later the log-on screen shows up as if I had just started Ubuntu.

It only happens on my 64bit Ubuntu, it works fine on other two PC's using 32bit Ubuntu's: I have tried 1.6... (ppa:ubuntugis/ubuntugis-unstable) and 1.7 (http://qgis.org/debian-nightly maverick main) with the same fatal results.

The paper-size ComboListBox menu can be successfully used with TAB and ARROW KEYS though, so it is something associated to the click action.

testing the crash here on 11.04 64 bit beta

installed

http://qgis.org/debian-nightly natty

Linux zwam 2.6.38-8-generic #41-Ubuntu SMP Tue Apr 5 19:30:49 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

no problem to report here

is it still valid on your machine?

will try ppa:ubuntugis/ubuntugis-unstable also

[rduivenvoorde]

installed qgis via ppa:ubuntugis/ubuntugis-unstable (after removal of other version) also

cannot reproduce this crash here neither, combobox looks ok

Is it only with this one combobox? Not with others?

Probably not a solution, but you could try to upgrade to natty within a couple of weeks?

Tested on r15737 with Kubuntu 10.10 64 bits. Everything OK.

Installed with this /etc/apt/sources.list entry:

# Nightly builds of the trunk   http://www.qgis.org/wiki/Download
deb http://qgis.org/debian-nightly maverick main
deb-src http://qgis.org/debian-nightly maverick main

Maybe you could try first this:

sudo apt-get purge qgis*
sudo apt-get update
sudo apt-get qgis

Also make sure you do not have qgis stable installed.

Replying to mayeulk:

Of course I meant:

sudo apt-get install qgis

Cannot reproduce that here. Sounds to me like it is a bug in another system component (otherwise, other processes would not crash too).

Actually, I tried the same on another 64-bit-Ubuntu PC and worked just fine. So, it more like a thing with this ACER laptop. I have instilled and removed many QGIS's, so next chance I have I'm going to try the purge command suggested above. By the way, it blows up when the ComboListBox is expanded by either mouse or keyboard action, but just flipping the page numbers (no pulling it open) works OK.
