Assertion (disk != NULL) at ../../libparted/disk.c

Error: Error opening /dev/sdg: Kein Medium gefunden
A bug has been detected in GNU parted.  Please email a bug report to 
address@hidden containing the version (1.6.9) and the following 
message:Assertion (disk != NULL) at ../../libparted/disk.c:1037 in 
function ped_disk_next_partition() failed.

I got the message when I started *qtparted* with a cardreader on USB bus 
with an SD card plugged in (and USB devices mapped to SCSI). When I 
clicked onto the symbol of the SD-card the card was already removed from 
the cardreader.
