Thanks sheen7334, as I see it the bug is related to the Imagemagick packages. I just bit the bullet myself and used the workaround proposed by Dan.
It seems to work, I can now scan and save as djvu , scan and save as pdf if I use automatic or jpeg compression but not if I use G3 or G4 tiff compression. Gscan2pdf used to work with the tiff compressions when making a pdf, but if this error is due to the packages in the workaround or due to something else I cant tell. By selecting automatic as compression I get a very small pdf too. The packages in the workaround involves: imagemagick libmagickcore2 libmagickwand2 pearlmagick -- locks when trying to save as PDF https://bugs.launchpad.net/bugs/424249 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
