Endless loop with sylpheed

Hello,

There is a problem aspell-0.60.2 when running with sylpheed-claws-1.0.0.
When opening the edit window for the first time it gets stuck in an
endless loop.  Sending it signal abort shows it gets stuck in this loop
in lib/find_speller.cpp, in function void BetterVariety::set_cur_rank():

        for (; *c != '\0'; c += p) {
          ++num;
          p = strcspn(c, "-");
          if (p == s && memcmp(m, c, s) == 0) {match = true; break;}
        }

The problem is when c has a '-' p is not incremented because on
subsequent loops c begins with '-' and p is zero.  The hyphen is in the
dictionary name and using dictionaries without variants avoids the
problem.

I think aspell should step over the hyphen as well as the chars matched
by strcspn(), for example, changing the first line thus allows it to
run:
        for (; *c != '\0'; c += p + 1) {

I've no idea what that does to the intent of the program, the above is
not supposed to be the solution but merely a hint at the problem.
