I am willing to send a fix for this if someone can indicate what the correct fix should be. My thinking is:
- Make the latex printer special in that it falls back if the formatter fails.
- Don't print the warning in the console (is there some kind of debug log I can print it to instead?)

Thanks @asmeurer. This is also related to issue #56 and PR #57.
I'll look into it for 4.2.

I didn't see those. Thanks for the reference.
I think this boils down to the fact that there is no way for frontends to change the printer precedence (in the qtconsole or the notebook). This is something that SymPy would like to have as well (we basically work around it by having options to init_printing
that cause various printers to not be enabled at all). That's a much bigger issue to fix, though.
That PR looks extreme, and would probably break things for people. For SymPy, it would actually work, because our printing isn't enabled without calling init_printing()
anyway, and we define our own png repr using latex/dvipng or matplotlib (and our printers do the right thing in this case, falling back to the text printer if matplotlib can't handle the LaTeX).
I'm not clear if the fix I'm suggesting would fix @flying-sheep's issue, unless it is also coming from LaTeX that matplotlib cannot render.

Here is a fix #65. It's maybe not the cleanest thing, but it works.
