Comment 4 for bug 923241

There have been a few patches to gdl-switcher.c since our version[1] (upstream=2648F, 2010-10-26)

One patch in particular may be of use[2], which ensures that the btns_per_row variable is always a positive nonzero integer. Looking at the backtrace, this seems to be the thing that's causing the divide-by-zero exception.
