#451 new defect

Matplotlib crash in savefig (png)

Description

The version of matplotlib included in the 64-bit installer (matplotlib version 1.3.1) causes python to crash when savefig is applied to save a png. This happens both from the GUI and when applied programatically. Does not happen e.g. for a pdf or jpeg, so seemingly a defect in a (lib)png dependency. Using backend "Qt4Agg".

I am experiencing this problem in my qgisplugin to, as do my users, can the version of mathplotlib / libpng be upgraded in the installer?

These are the content of error rapport in visual studio:

Replying to silyko:

The version of matplotlib included in the 64-bit installer (matplotlib version 1.3.1) causes python to crash when savefig is applied to save a png. This happens both from the GUI and when applied programatically. Does not happen e.g. for a pdf or jpeg, so seemingly a defect in a (lib)png dependency. Using backend "Qt4Agg".

I've experienced the same problem on Windows but it's OK on Ubuntu & fedora. A workaround is to produce Tiff.
