-- Information about the crash:
It erroneously believed that my scanner was busy despite my cancelling an entry of the print-queue, pasuing the scanner, and unpusaing the scanner. The print KCM believed it to be idle.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Skanlite (skanlite), signal: Segmentation fault
