i have found a workaround to the problem: downgrade libgtk2.0-0 from the candidate 2.11.6-1ubuntu3 to 2.10.11-0ubuntu3, and restart Opera.
wget http://ubuntu.dlf.ge/ubuntu/pool/main/g/gtk+2.0/libgtk2.0-0_2.10.11-0ubuntu3_i386.deb sudo dpkg -i libgtk2.0-0_2.10.11-0ubuntu3_i386.deb different architecture builds can be found here: http://ubuntu.dlf.ge/ubuntu/pool/main/g/gtk+2.0/ and many other repositories. this workaround also fixes the bug with OpenOffice application crashing on start. -- [gutsy] opera slow down/crash when browsing a page with flash (non-free) content https://bugs.launchpad.net/bugs/131212 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
