Hm, I see that every string variable declared there has 2 extra characters, and yet the author have managed to make a mistake... these extra chars don't seem needed.

Those extra characters made me believe the intention was setting the
NULL character, therefore I used that solution in my patch.

It was wrong to call ide_fixstring() on those "long" stings without first setting their last byte to 0 -- this way that function just copied the garbage at the end of the passed unterminated strings. I suggest that you get rid of those extra bytes as well, and use the "%.<n>s" format specifiers.
