Comment 54 for bug 617885

Had the same bug, and this thread helped point me in the right direction. I'm not sure if my response is appropriate, as I'm sure more than a handful of less technical users will find this thread (it's the first few hits for 'gparted crash' search results.) If not, I apologize in advance. I solved the issue by using git to pull the current version of gparted, and building it. From a stock Maverick desktop 64 bit, system, I ran (as root):

# aptitude install git gnome-common libglib2.0.dev uuid-dev libparted-dev libgtkmm-2.4-dev

Then changed to the /tmp directory, ran

# git clone git://git.gnome.org/gparted

# make

# make install
