Attempt to unlock mutex that was not locked

Version:

Ubuntu Trusty (14.04)

Problem:

GTK-2 apps crash with the error: "Attempt to unlock mutex that was not locked". The problem occurs when using ppa's that use error phrone gtk-2 libs (like atareao's pushbullet ppa).

Solution

• see: https://bugs.launchpad.net/ubuntu/+source/gtk+2.0/+bug/1376530

My solution:

sudo sudo ppa-purge ppa:atareao/atareao
sudo apt-get install libgtk2.0 libgtk2.0-dev/trusty libglib2.0-dev/trusty libglib2.0-bin/trusty libpango1.0-dev/trusty libpango-1.0-0/trusty libpangocairo-1.0-0/trusty libpangoft2-1.0-0/trusty libpangoxft-1.0-0/trusty gir1.2-pango-1.0/trusty libgtk2.0-cil/trusty libpango1.0-0/trusty

Reinstall packages, e.g.

sudo apt-get install acroread wine1.7 ...
