These issues seem to be highly dependent on the driver used (and thus the scanner used).
In the trace there is a warning about "device in use". Is hitting delete actually necessary? Does it work if you just cancel a scan in progress and then try to do another scan?

Title:
  simple-scan; segfault after page delete

Status in Simple Scan:
  Incomplete
Status in “simple-scan” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: simple-scan

  Ubuntu 10.10,i386

  $ dpkg -la | grep simple-scan
  ii  simple-scan                          2.32.0-0ubuntu4

  My Printer/Scanner is HP Deskjet F2480 (I hope this information is not
  important)

  I can repeat steps those finish with segfault.
  1) start simple-scan (from CLI)
  2) start SCAN
  3) break SCAN in the "middle" of page (STOP button in simple-scan GUI)
  4) use mouse right button and select DELETE
  5) repeat step 4 (try another DELETE)
  6) start SCAN (and you have segfault!)

  Details:

  $ simple-scan
