I'm not sure why this was marked as affecting ubuntu-friendly. Both oneiric and ubuntu-friendly are EOL so this bug is out of scope for either. I'll return this to affecting libcairo, as the upstream bug report refers to that. Thanks!

Annullato When the Gtk: gtk_widget_size_allocate() errors happen I can see the tabs width becoming very small and this is usually a few seconds before the crash. If I resize the browser's window the tabs return to the correct width and I get a few extra seconds before it crashes. Visiting certain sites (like ebay) and opening new tabs seems to give more chances to crash, but not always. Upgrading Chromium to 15.0.874.106 (Build 107270 Linux) from the proposed repository did not help. Nor it did disabling all the extensions. I'm running a Ubuntu 2D session.
