[DRE-maint] Bug#714501: drawBlendedUTF8() crashes when passed an empty string

[Joseph Nahmias]

Package: ruby-sdl
Version: 2.1.2-3
Severity: normal

Hello,

While debugging a problem in magicmaze, a game which uses ruby-sdl, I
tracked down the cause to a call to drawBlendedUTF8() which is passed an
empty string.  This crashes the game.  I have implemented a workaround in
magicmaze/1.4.3.6+dfsg-2, but I feel this should really be addressed
upstream.

Thanks,
--Joe
