Comment # 2 on bug 916210 from Dominique Leuenberger

There was a question raised in bug 905444#c1 which never got answered, that's
why this bug has been closed (and it's not exactly the same bug: the last bug
was about a crash - you request a version update)

"""
We released an update for GTK 2.24.25 that addressed a bunch of those mutex
unlock issues.

Can you please verify that you have this update installed ? Does the problem
persist after installing GTK 2.24.25?
"""

Anyway, we'll see to get this updated to something more recent.
