Confirmed; the rows and columns fields for all data types must be integers, and sparse indices must be integers. And just to clarify, was this a text file you formatted yourself to be read into Octave, or one created in Octave using the save function?

I have an Octave-format text file that (inadvertently) contained a column index of '1e+05' in a sparse matrix. This confused Octave, of course, but the resulting error messages was quite unhelpful:

In particular, there was no indication of where in the (1.6MB compressed) input file the error occurred. Fortunately, JordiGH helped me track it down on IRC, but more helpful error reporting for corrupt input would be very appreciated.
