System Information
Archlinux + nvidia driver

Blender Version
Broken: 2.76 RC (from official standard archlinux repos)
Worked: (not sure which version. used to work fine in earlier version though because i used it all the time)

Short description of error
segementation fault when doing "export UV layout" for a png.
*work around for now, I export to a SVG then manually convert to png for now. That seems to work OK.

Exact steps for others to reproduce the error
I have UV coords visible on the uv screen. I click "UVs" -> "Export UV Layout." I select png and execute. segfault.

Here is my output from console:
PyContext 'window' not found
Fatal Python error: PyThreadState_Get: no current thread

Segmentation fault (core dumped)

hi,
I cannot confirm this on osx. works ok here. Please drag drop error files to git rather than paste wall of text.

Fixed the 'missing xxx pycontext' messages, would not really expect those to cause the crash though.

Also, please try with latest RC3 from our website, we cannot accept reports based on packages from linux distros, only those based on our own official builds.

This is infact unrelated to "Export UV Layout" script.

The problem is that official Blender builds use Python3.4, but Archlinux used Python3.5, which changes behavior WRT PyThreadState_GET.

We have a fix so Blender works with Python3.5 and 3.6, so Ill just back-port that to the release.

blender/blender@4aad17c622 needs to be backported to the release.

Re-opening and assigning to regressions so we dont forget.

Campbell Barton changed title from ~~Export UV Layout to PNG not working~~ to PyC_IsInterpreterActive fails w/ Py3.5+, (was: Export UV Layout to PNG not working)
