I started gparted from the GNOME menu and while it was searching my devices for partitions, it crashed and apport presented me a report in the GNOME panel.

Here please find some technical info about my Ubuntu installation:
Release: 10.10 beta AMD64, installed from Alternate ISO image on USB thumb drive.
package version: gparted 0.6.2-1ubuntu1 from http://ftp.ticklers.org/archive.ubuntu.org/ubuntu/ maverick/main amd64 Packages

Running from the terminal makes the following happen:
~$ gksudo gparted
======================
libparted : 2.3
======================

glibmm-ERROR **: 
unhandled exception (type std::exception) in signal handler:
what: basic_string::_S_create

aborting...


Figuring out that partitionmanager uses libparted, too, I installed partitionmanager with all necessary KDE libraries to see what happens upon starting that programme.

partitionmanager starts up and seems to work fine.

For me gparted is not that important, since terminal commands can do as well. But it would be more comfortable to have gparted back working.
If I can provide you with further relevant information, let me know.
