  1. Go to https://github.com/RasmusLindroth/tut/releases/tag/0.0.14
  2. Click on tut-amd64
  3. Segfault!

Tested build from source from last night, on amd64, Gentoo.

From the terminal when it crashes:

@alcinnz does the terminal output give any hints on how I can further debug? If you cannot reproduce, it is probably an issue on my end ... or it may be how I have compiled the dependencies on Gentoo (which will affect how Odysseus is packaged for Gentoo) ...

A gdb stacktrace would be useful.

I think a theory just occurred to me. Maybe it's a desktop-integration I've implemented specific to the Pantheon and late Unity desktops, and I'm not recovering well enough from errors there. I'll try adding some more NULL checks tonight and have you test if that fixes it.

Try the latest master, or failing that commenting out src/Traits/init.vala line 22. Does either of those fix it? Though looking at that log again I might be barking up the wrong tree.

If you run it under GDB what does running bt after the crash output?

Still broken.

Hopefully this helps?

Maybe I cited the wrong line in that file, but never mind. I definitely was barking up the wrong tree.

Now try the latest master, this might fix it.

If the issue was that you were lacking the standardized environment variable telling me where to place downloads...
