EOF crashes on importing the following .gpx converted to .gp5: http://www.abysslord.com/megadeth/tabs/super/05-Off_The_Edge.gpx .  EOF crashes after saying to me: 'invalid note length of 19 and is probably corrupted'. Since Guitar Pro gives me an error about a tuplet when saving to .gp5 it might have something to do with that. 

That is definitely not a valid note length, which indicates what type of note it is. The formula for a value of n is

1 / 2^(n+2)

ie. a value of -2 is a whole note (1 / 2^0 == 1), and a value of 4 is a 64th note (1 / 2^6 == 1/64). There is no way that a 1/2097152 note is valid in Guitar Pro 6, it probably wrote a corrupted value when converting it to GP5 format.

 

I converted it to GP5 with the TuxGuitar 1.3 build Shrubbery posted (http://customsforge.com/topic/2235-guitar-pro-5/?do=findComment&comment=11971) and I was able to import that into EOF just fine. Here's the GP5 file:
