Title:
  lockup on saving a pdf

Status in Simple Scan:
  Expired

Bug description:
  Using simple-scan version 2.32.0.1 on OpenSUSE 11.4 under Gnome I get
  a total lockup of simple-scan with no error message when trying to
  save a document (any document - text/photo/multipage/singlepage...) as
  a pdf.  The issue seems to be repeatable approx 80% of the time.

  I launched simple-scan from the command line, scanned one page (150dpi
  text mode), clicked save as... chose pdf from the document type
  selector at the bottom of the save dialog, clicked save, and it locked
  up.  Tail of the debug output is at the base of this message.

  Printing works fine, including 'print to pdf', so the workaround is
  straightforward.

  Debug output...
