Comment 5 for bug 556670

Because I get this problem in GIMP and Inkscape but not MyPaint, I decided to make a list of dependencies shared by GIMP and Inkscape _but not MyPaint._ Here is the list, with each package name followed by the version I have installed (all are from the official Ubuntu repositories):

libatk1.0-0 (1.32.0-0ubuntu1)
libcairo2 (1.10.0-1ubuntu3)
libfontconfig1 (2.8.0-2ubuntu1)
libfreetype6 (2.4.2-2ubuntu0.1)
libgdk-pixbuf2.0-0 (2.22.0-0ubuntu1)
libgtk2.0-0 (2.22.0-0ubuntu1)
liblcms1 (1.18.dfsg-1ubuntu2.10.10.1)
libpango1.0-0 (1.28.1-1ubuntu3)
libpoppler-glib5 (0.14.3-0ubuntu1.1)
libx11-6 (2:1.3.3-3ubuntu1)
zlib1g (1:1.2.3.4.dfsg-3ubuntu1)

Of course, this doesn’t include dependencies _of_ dependencies... for instance, MyPaint requires PyGTK, and I’d imagine that in turn requires libgtk. Anyway, this is what I have for now.
