Sorry- I figured people interested at looking into
the problem would set up test documents.
Some additional information:
The 'image' dir has 1670 image files in it. Its a
common image store for many projects. I mention
this as the debug output also seems to spend time
in mangle.c, apparently looking at every file
regardless if it is required for the project or
not. This dir does contain quite a few files. I
have the option set under the share: mangled names
lib/util.c is the routine it seems to spend much
of its time in while working with TIFFs.
One thing I didn't test that I will today, is to
accretion if it is perhaps the amount of files in
the dir. When I converted the files to other
formats, they were loaded outside of the main
take care and thanks for your interest.
