Bug#359196: gdmgreeter segfault with some themes

[Andrea Vettorello]

Package: gdm
Version: 2.13.0.10-2
Severity: normal

With some themes, for example ayo, debian-dawn, blueswirl, i can always 
crash gdmgreeter. In a terminal after launching "gdmthemetester 
console blueswirl", clicking with the mouse pointer to the "Username:" 
label, gdmgreeter segfaults.
I've some assertion on the terminal, but this doesn't happen with with all the
themes.
