Python claims to be unable to import pyplot. Apart from that, it has been running absolutely fine. I tried different versions of matplotlib, the one provided in my package manager (apt-get) and two (stable & last stable) releases compiled from source. I reinstalled all packages containting "python" on my system (Ubuntu 14.04 LTS). This error still occurs and prevents me from using pyplot. What should I try next?

You have an afm font file with a badly formed header. I thought this was fixed on the master branch though....

Okay, is there a way to get an afm font file with a nicely formed header? How could I try to solve this problem? Thomas Caswell wrote > You have an afm font file with a badly formed header.

Also try deleting your font cache. Have you tried with the master branch?
