It's not that easy to do the untangling even manually though. – Szabolcs

Maybe you could turn it into a puzzle and let other people do the untangling :-) – Heike

I could make a web based game, and feed all my graphs to the visitors.
SE is a big game, isn't it? :D – Szabolcs

This is not a discussion forum. We follow a Question & Answer format instead. Therefore it is appropriate to put extensions and clarifications to your original question in the Question itself (by editing it). I have moved your content for you in this case.

@QuantumDot This question just got bumped by Community♦ because it has no positively voted answer. Please post the method in your comment above as a self-answer. If you don't I shall edit my answer to include it.

comment ToExpression from commandline
TeXForm conversion is quite complicated. For a sample run this in the Notebook interface on a fresh kernel: TracePrint[ ToExpression["x=4-2", TeXForm], TraceInternal -> True ]. For me (in version 10) this also hung after crashing TeX.exe. I think it is possible that an external command (e.g. to TeX.exe) attempts an invalid action (display?) and this is what in turn hangs Mathematica.

comment Part specification error only in LogPlot
I believe this question is a duplicate, specifically the issue of Plot first attempting a symbolic evaluation of the function. Can anyone find it?
