Comment 58 for bug 424249

I have experienced the same problems as noted above.

Here is what I did to work around.

1. I installed the imagemagick-6.5.8.3 source package, generated the .deb using prevu, and installed the resulting package on Karmic Koala on an amd-64 PC. My packages have version number 6.5.8.3-1~9.10prevu1.

2. I ran gscan2pdf with the new package and experienced the same hanging at 50% on saving to PDF.

3. I deleted my ~/.gscan2pdf file and re-ran gscan2pdf. This time, I was able to save successfully to PDF. Interestingly, the progress dialog on saving still hung at 50% but then very rapidly concluded the action and disappeared.

4. Note: on scanning lineart, there is no compression and indeed no choice for compression other than "none". On scanning grayscale, I chose no compression again.

In sum, changing the imagemagick suite to the latest on the Debian/Ubuntu source repositories and removing the old ~/.gscan2pdf file did the trick.

I am happy to provide more information if I am told what to send. I would love to see this bug squashed: gscan2pdf is such a good package.

Thank you for your efforts.
