Added the attached printfs. Here's the output:

Aborted (core dumped) This is a buffer overrun by one byte. You can see clearly that all the other color depths (besides DeviceGray) add an extra byte to account for this overflow. Only the DeviceGray one does not, adding one to the data_length calculations for DeviceGray fixes the problem. Please let me know if you want any other printfs or information in specific places. ** Patch added: "Printfs" https://bugs.launchpad.net/ubuntu/+source/simple-scan/+bug/664608/+attachment/2793651/+files/debug-printfs.patch -- You received this bug notification because you are a member of Simple Scan Development Team, which is the registrant for Simple Scan. https://bugs.launchpad.net/bugs/664608 Title: simple-scan crashes when saving to PDF Status in Simple Scan: Triaged Status in “simple-scan” package in Ubuntu: Confirmed Bug description: Binary package hint: simple-scan I can not save a scanned image or textfile.
