There's a discussion on the same issue on hamster's github page, https://github.com/projecthamster/hamster/issues/46
In there, jarrodmoss <https://github.com/jarrodmoss> said I have the same issue. Downgrading libcairo2 to the version in Precise > (1.10.2) fixes it for me. > > Upgrading libcairo to 1.12.12 (version from Raring) also fixes the issue. > Seems like a bug in cairo that has already been fixed. > And I checked libcairo2 in debian. It seems next update will be version 1.12.14 and it is still in experimental at the time I'm composing the email. So I guess there is a long time before it gets available in any wheezy update. I live on hamster so I will try to figure out what I can do to speed up the new integration. Anyway, this issue needs to be moved to libcairo2's bucket.
