[Eric Pettersen]

If the Python traceback is accurate, it's crashing in this line of set_user_agent() in chimerax.ui.widgets.htmlview:

from chimerax.core.fetch import html_user_agent

I don't see anything in core/fetch.py at the global scope that could possibly cause a problem -- there aren't even any other imports. Is it a problem with locating fetch in sys.modules?

I don't even know who to assign this ticket to really. It is on a Windows 8 machine. Would that be an issue?

--Eric

[Greg Couch]

I agree that the segfault doesn't make sense. It might be data related or a bug in the graphics driver. The current graphics driver is 461.72 and they have 391.35.

[Tom Goddard]

Just a wild guess, but maybe this is the "garbage collection" crash we have seen many times on Mac. That one happens at random places in the code since it happens when the garbage collector runs.

[Eric Pettersen]

Well, maybe, but those other garbage collection crashes "felt" like they were after using ChimeraX for awhile, whereas this one is clearly at startup. Nonetheless, maybe. Anyway, I don't think there's anything useful I can do to debug this further without more info.

[Tom Goddard]

Yep, missed that, it is building the UI at startup. Agree there is nothing to do about it. Chalk it up to Windows 8 -- unsupported.
