palimpsest crashed with SIGSEGV when pressing verify filesystem more than ones

[blippe]

Binary package hint: gnome-disk-utility

in ubuntu 10.04 disk tool
if I select a partition (for example an unmounted FAT32 or a NTFS) and then press the button to check the file system it very quickly pop up a dialogbox saying the filesystem is good. (I wonder how much checking it actually do, since if I run chkdsk in WinXP it takes ages)
if I then close that dialogbox en press same button again, to check the same partition again (one or two times) the program crashes and starts this bug report.

1)$ apt-cache policy gnome-disk-utility
