RE: gialog immediately segfaults

["Jesse D . Sightler" <jsight pair com>]

Well, I haven't looked at the source yet, but from this backtrace
I was able to find the problem.  :-)

Basically, if I run 'gdialog --yesno "test" 80 80' the program core
dumps, but if I give it something longer like:
 'gdialog --yesno "test is some testing code to find out what is going on here and warp" 80 80'

It executes beatifully.  Apparantly label_autowrap() is the source of the problem?
