Comment 4 for bug 298188

have exact same problem under Ubuntu 8.10
I'm using XSane 0.995 to scan a document and save it under the standard format "out.pnm"
trying to open this document with "eye of gnome" (eog) 2.24.1 gives error message:
             PNM loader expected to find an integer, but didn't

the pnm format is supported by the package libimlib2
Ubuntu 8.10 uses the following package: 1.4.0-1.1ubuntu1.1

looking around I've found an updated version 1.4.0-1.2ubuntu1 available under Ubuntu 9.04 development
installing above package did solve the problem.
package can be installed from here:
