Summary: Crash when hovering over the word kai (και) in the LXX,

Initial Comment:
If I hover over the word kai (και) in the LXX module, BibleTime crashes with the attached backtrace.  See also attached screen shot to show what my setup is, in case that is relevant.  I'm using the StrongsRealGreek module, I haven't seen if it happens with other Strongs modules yet.  This does not occur if I hover kai in WHNU.

Versions: 
BibleTime 1.7.beta3
libsword: 1.5.9-8.1ubuntu1

It doesn't hurt to make a check, just to be sure it works in any case, so
I added it to
svn code:
if (value.size() > 1 && value.at(1).isDigit()) {

Message:
I can confirm that the same crash happens if I switch to the more common
StrongsGreek module.  This makes BibleTime very crashy for me -- I've got
to be very careful where I point my mouse.

Thanks!
